Unsplash vs Pexels vs Pixabay for Bulk Downloads

Most comparisons of the free stock libraries are written for someone hunting a single hero image. That’s a different problem from the one I care about here. When you need one photo, you can afford to browse all three sites, agonise, and pick the best. When you need forty, browsing stops being viable and the differences that matter shift entirely — to catalogue depth on unglamorous search terms, to how consistent the results look side by side, and to whether the licence survives however you’re planning to use them.

I’ve pulled a lot of images out of all three. Here’s what actually separates them once volume enters the picture.

The Short Version

	Unsplash	Pexels	Pixabay
Owned by	Getty Images	Canva	Canva
Attribution required	No (strongly encouraged)	No	No
Commercial use	Yes	Yes	Yes
Media types	Photos	Photos, video	Photos, illustrations, vectors, video, music, SFX
Aesthetic	Editorial, moody, consistent	Bright, commercial, clean	Highly variable
Strongest at	Lifestyle, landscape, abstract	People, business, product	Illustrations, niche objects, diagrams
Weakest at	Anything mundane or specific	Abstract and artistic	Consistent quality

The single most useful thing to know: Canva owns two of the three. Pexels and Pixabay were both acquired in 2019, and Getty acquired Unsplash in 2021. That consolidation explains some overlap you’ll notice between Pexels and Pixabay results, and it’s worth factoring into any assumption that searching all three gives you three genuinely independent catalogues.

Where the Licences Actually Differ

All three use custom licences rather than Creative Commons, and for most purposes they converge: free, commercial use permitted, no attribution legally required, no permission needed.

The differences show up at the edges, and the edges are where people get hurt.

Selling the image itself is prohibited everywhere. You can’t download a Pexels photo, put it on a print-on-demand poster, and sell it. You can put it in a brochure advertising your business, because the image is supporting a product rather than being the product. That line is clearer in the terms than people expect, and it catches a surprising number of print-on-demand sellers.

Building a competing library is also prohibited everywhere — you can’t scrape all three and launch your own stock site. Fine, obviously.

Identifiable people are the genuine trap. The photographer secured a model release covering the photograph. That does not extend to you implying that person endorses your product, or using their face in a context that could be read as defamatory. Every one of the three says something to this effect, and every one of them says it in a paragraph nobody reads. If your forty images include faces and they’re going into advertising, this is the clause to actually read.

Attribution is where the practical difference lives. None require it. Unsplash asks for it and its community expects it strongly enough that skipping credit on a widely-seen piece will occasionally earn you a comment. Pexels and Pixabay are more relaxed. For a blog post, crediting costs a line and buys goodwill. For packaging or a printed piece where a credit line would look strange, all three permit omitting it.

One thing that has genuinely changed: Unsplash now runs a paid tier alongside the free catalogue. The free licence still covers the free images, but search results mix the two, so check what you’re grabbing before assuming a whole batch is free. Terms across all three have shifted more than once — if the stakes are real, read the current version rather than a summary written by anyone, including me.

Catalogue Depth: The Thing That Decides It

Aesthetic preferences are subjective and everyone’s comparison writes the same three sentences about them. Depth on boring searches is objective and nobody tests it, so that’s where I’d point your attention.

Search “sunset” and all three return more beautiful images than you could use in a lifetime. Search “warehouse inventory shelving” and the field thins dramatically. Search “person using accounting software” and it collapses.

The pattern I’ve found consistently:

Unsplash is deepest on the photographic and atmospheric — landscape, architecture, texture, moody lifestyle. Its contributor base skews toward people who take photography seriously, and it shows. It’s noticeably thin on the mundane and specific. If you need a photo of a particular kind of office equipment being used in a particular way, Unsplash will hand you something beautiful and adjacent instead.

Pexels is the strongest general-purpose option for commercial subject matter. People at work, product shots on clean backgrounds, food, business scenarios. The aesthetic is brighter and more conventionally commercial than Unsplash’s, which is a downside if you want distinctiveness and an upside if you need images that will sit quietly behind body copy without competing.

Pixabay has the widest range of media types by a distance — illustrations, vectors, diagrams, video, music and sound effects alongside photos. When your batch needs icons or simple illustrations rather than photography, it’s frequently the only one of the three with anything usable. The trade-off is quality variance. Pixabay’s bar for uploads has historically been lower, so results range from professional to something taken on a phone in 2012. For bulk work this matters more than for single-image work, because you’ll be scanning a grid of results rather than examining each one.

What Changes When You Need Forty

Single-image sourcing and bulk sourcing are different activities, and three things flip.

Consistency starts outranking individual quality. Forty images that each look great but were shot by forty photographers with different colour grading will look like a ransom note when laid out on one page. This is where Unsplash’s strong house aesthetic becomes a genuine advantage — its results hang together. Pixabay’s variance becomes a real cost.

Search time dominates. Running the same query across three sites, mentally deduplicating, and tracking which ones you’ve already grabbed is the bulk of the work. It’s also why our bulk image downloader queries all three at once and returns the set as a single ZIP — the searching is the slow part, not the downloading.

File size becomes a project. All three serve full-resolution originals, commonly 4,000–6,000 pixels at 4–8MB. Forty of those is around 240MB of images that cannot go on a website unchanged. That’s a resize, compress and convert pass over the whole batch, which the bulk sourcing guide walks through in order.

Which One Would I Actually Search First?

Building a marketing site or blog and you want it to look considered. Unsplash. The aesthetic consistency across a set is worth more than any individual image, and it’s the library least likely to make your site look like everyone else’s — though “least likely” is doing real work in that sentence, since Unsplash’s most popular images are extremely widely used.

You need commercial subject matter and you need it to exist. Pexels. Business, people, product, food. Less distinctive, far more likely to actually have the thing you searched for.

You need illustrations, vectors, or anything that isn’t a photograph. Pixabay, and it’s not close. It’s also the one to try when a search fails on the other two, because its long tail is genuinely longer even if the average quality is lower.

You need forty images and you don’t want to run the query three times. Search all three at once and sort it out from the combined results. That’s the case our downloader was built for.

Honestly? For most bulk work I search all three and cherry-pick, because the overlap is smaller than you’d expect and the cost of checking is one search instead of three. The aesthetic argument matters when you’re picking two images. When you’re picking forty, availability wins.

The Part That Comes After

Whichever library you use, the images arrive far too large, named after a database ID, and in whatever format the photographer uploaded. That’s the same problem regardless of source.

Resize the batch to your target width first, compress at around quality 80, then convert to WebP — in that order, so you’re not stacking lossy passes or compressing pixels you’re about to throw away. The bulk resizer, compressor and format converter each take the whole folder at once, and the complete compression guide covers where quality 80 should move for your content.

Searching all three libraries in one pass is what the bulk image downloader does — one query across Pixabay, Unsplash and Pexels, everything back as a single ZIP. Then get the batch web-ready with the bulk resizer and compressor, right in your browser with nothing uploaded anywhere.

Frequently Asked Questions

Which is better, Unsplash, Pexels or Pixabay?

It depends on subject matter rather than overall quality. Unsplash is strongest for photographic, atmospheric and lifestyle imagery with a consistent house aesthetic, which matters when you need a set of images to look coherent together. Pexels has the deepest catalogue for commercial subjects — business, people, product and food. Pixabay carries the widest range of media types including illustrations, vectors, video and audio, but with more variable quality. For bulk work, searching all three and cherry-picking usually beats committing to one.

Do I need to credit Unsplash, Pexels or Pixabay?

None of the three legally require attribution. Unsplash actively encourages it and its community expects it, so crediting is worth the line of text on anything widely seen. Pexels and Pixabay are more relaxed about it. Where a credit line would look out of place — packaging, print collateral — all three permit omitting it. Licence terms have changed more than once across all three, so check the current version if the use is commercially significant.

Can I use free stock photos in a product I sell?

You can use them in marketing for a product you sell. You cannot sell the image itself as the product — putting an unaltered stock photo on a print-on-demand poster or reselling it as a download is prohibited across all three libraries. The other significant restriction concerns identifiable people: the photographer's model release does not extend to implying that person endorses your product, so photos containing faces need extra care in advertising contexts.

Are Pexels and Pixabay the same company?

Both were acquired by Canva in 2019, so they share an owner while operating as separate libraries with separate catalogues and separate licences. Unsplash was acquired by Getty Images in 2021. This is worth knowing if you assume searching all three gives you three fully independent sources — there is some overlap between the Canva-owned pair, though their catalogues remain largely distinct in practice.

How do I download multiple stock images at once?

None of the three libraries offer a native bulk download for search results — the standard flow is one image at a time. BulkImagePro's bulk image downloader searches Pixabay, Unsplash and Pexels together from a single query and returns the selected results as one ZIP, which removes both the repeated searching and the per-image saving. The downloaded files will be at full resolution, so plan on a resize and compress pass afterwards.

Why do stock photos from these sites make sites look generic?

Because the most popular images on each library get used enormously widely, and search rankings concentrate everyone on the same top results for common terms. Searching a more specific phrase, going deeper than the first row of results, and mixing sources all help. The more reliable fix is to use stock for supporting and background imagery while shooting your own photos for anything that carries your actual message — product, team and work.
