TinyPNG Alternative: When Browser-Only Wins

Pixeltools is a good TinyPNG alternative if you compress JPGs and WebPs, want no batch cap, or do not want your files uploaded. It is not a full replacement if you mainly shrink PNGs, because TinyPNG's PNG results are better. Checked September 2026.

The core difference is where the work happens. TinyPNG's web tool sends your images to its servers. The [pixeltools image compressor](/compress) runs entirely in your browser, so nothing is uploaded and there is no account. We are the tool being compared here, so we say plainly where TinyPNG is stronger below, in the same spirit as our [pixeltools vs Smallpdf](/blog/pixeltools-vs-smallpdf) write-up.

Pick TinyPNG for PNG-heavy work, its API and its plugins. Pick pixeltools for private, unlimited, no-signup batches of JPG and WebP.

TinyPNG's free web tool takes up to 20 images per batch, at up to 5 MB each. Its homepage lists JPEG XL, AVIF, WebP, JPG, PNG and APNG for compression, and says free users can convert up to 3 images.

Beyond the free web tool there are paid Web Pro and Web Ultra plans. Check tinypng.com for current prices, since they change.

The developer API has a free tier of 500 compressions per month, per the TinyPNG developer page. It handles AVIF, WebP, JPEG and PNG, and TinyPNG offers official WordPress and Figma plugins, plus Make and Zapier integrations.

These are limits worth knowing before a big job. A 60-image product shoot means three batches, and any photo over 5 MB needs a plan or another tool. (TinyPNG limits taken from its own site, September 2026.)

Pixeltools compresses JPG, PNG, WebP and GIF (animated GIFs have their own compressor) in your browser, with no upload and no batch cap in the code. Everything runs through the browser's canvas.

A few details we know because we wrote them. The quality slider defaults to 80% and drives the browser's JPG and WebP encoders. Files over 50 MB trigger a warning that they may be slow, not a hard rejection, and the practical ceiling is your device's memory. Batches download individually or as one ZIP built in the browser. You can keep each file's format or switch the output to JPG, PNG or WebP.

The result: on a phone or laptop, a 100-photo folder compresses with no limit counter and no waiting on a server. The tradeoff is that your own hardware does the work, so very large files on old devices are slower.

TinyPNG is better at shrinking PNGs, and this is the biggest gap. TinyPNG is known for lossy palette reduction, which cuts the color count while keeping transparency. Pixeltools does not do that.

Our PNG output goes through the browser's own canvas encoder. That is lossless, so transparency stays intact, but the quality slider does nothing for PNG. The interface hides the slider and shows a note that PNG is lossless. The practical result is that a PNG often stays close to its original size in pixeltools, where a palette-quantizing tool can cut it substantially.

If you have a large PNG and want it much smaller, you have two options here. Convert it to WebP, which keeps transparency and responds to the quality slider, or use TinyPNG for that file. Our [PNG compression guide](/blog/compress-png) explains the tradeoff in more depth.

TinyPNG wins on automation and ecosystem. It has an official API, a WordPress plugin, a Figma plugin and Zapier and Make connectors. Pixeltools has none of these: it is a web page you use by hand.

If you run a WordPress site and want every upload compressed automatically, or your build pipeline should shrink images on deploy, TinyPNG's API is the right shape and its 500 free compressions a month may cover a small site. A browser tool cannot do that.

TinyPNG's free web tool also lists AVIF and JPEG XL as compression inputs. Pixeltools' compressor accepts JPG, PNG, WebP and GIF. Conversions between more formats live in the separate [image converter](/convert).

So the honest split is workflow. TinyPNG suits recurring, automated, PNG-focused work. Pixeltools suits one-off manual batches where privacy and no limits matter more.

Pixeltools wins on privacy, limits and friction. Your files never leave your device, which matters for client work, ID photos, unreleased designs or anything under an NDA. A web tool that uploads files asks you to trust its retention policy. A browser tool removes the question.

It also has no batch cap or per-file size limit in the code, no account and no paid tier to hit. The [compress tool](/compress) pairs with [resize](/resize) when dimensions matter more than quality: a 4000 pixel photo shrinks far more by resizing than by any quality setting. For a fuller method, see how to [reduce image file size without losing quality](/blog/reduce-image-file-size).

If you are comparing other free tools too, our [TinyWow alternative](/blog/tinywow-alternative) page covers the upload question for a broader suite.

Use TinyPNG for PNGs, automation and plugins, and pixeltools for private, unlimited JPG and WebP batches. In practice many people use both.

Choose TinyPNG if your files are mostly PNG and you need them as small as possible, you need an API or WordPress plugin, or you are inside the 20 image and 5 MB limits and do not mind uploading.

Choose pixeltools if you have photos or WebP files, more than 20 at a time, files over 5 MB, sensitive images, or you do not want to sign up. For a transparent PNG you want small, convert it to WebP first.

Other alternatives exist, such as Squoosh, ImageOptim and ShortPixel, and some suit specific needs better than either tool here. TinyPNG details were last checked in September 2026 and may change.
