TinyPNG alternatives that don't upload your photos
Same job, no upload.
Compare TinyPNG with tools that compress in your browser instead of on a server.

Side by side
How they compare
TinyPNG is good at what it does, and for most photos the result is excellent. The thing worth knowing before you use it is where the compression happens: your image is uploaded to Tinify's servers, processed there, and sent back. Their own FAQ says files are retained for up to 48 hours before deletion.
For a holiday snap that's fine. For a client's unreleased product shot, a scan of an ID document, or anything covered by an NDA, the question stops being about compression quality and becomes about whether the file should be on someone else's machine at all.
The alternatives below split cleanly on that line. Squoosh and ImgKit do the work in your browser — the file never travels. TinyPNG and iLoveIMG upload. Neither approach is wrong; they're answers to different questions.
| ImgKit | TinyPNG | Squoosh | iLoveIMG | |
|---|---|---|---|---|
| Images sent to a serverThe one row that can't be undone — once a file is uploaded, you're trusting a retention policy. | No — everything runs in the browser | Yes — kept up to 48 hours, in its own words | No — runs in the browser | Yes |
| Account required | No | Not for the free web tool | No | Needed for larger files and some tools |
| Batch processing | Yes, unlimited | Up to 20 images at a time | No, one image at a time | Yes, with limits on the free tier |
| Compress to an exact sizeWhat you need when a form rejects anything over 50 KB. | Yes — compress to an exact KB | No | No — quality slider only | No |
| Third-party trackersOpen devtools, reload, and read the Network panel — it takes about ten seconds. | None. Cookieless page counts only | Google Analytics | Google Analytics | Google Analytics via Google Tag Manager |
| Price | Free | Free tier, paid API | Free | Free tier, paid plans |

Being fair about it
What each one does better
If you want compression built into your deployment pipeline, TinyPNG's API is the better tool — it's well documented, reliable, and a browser-based tool can't plug into a build server at all. The same goes for its Photoshop, Figma and WordPress plugins.
- ImgKit
- Weaker than the desktop apps on very large batches, since a browser tab has less memory to work with than a native program.
- TinyPNG
- A well-regarded API, official Photoshop and Figma plugins, and a WordPress plugin — none of which a browser-only tool can offer.
- Squoosh
- Simpler for a single image, made by Google's Chrome team, and the only one here that can write JPEG XL and QOI. Its compression is excellent — ImgKit uses the same two encoders.
- iLoveIMG
- Mobile apps for iOS and Android, a full PDF toolkit alongside the image tools, and an interface translated into far more languages.

Good to know
Questions, answered
How do I make a photo exactly 50 KB?
Switch to Target size and enter 50 KB. ImgKit tries quality levels until the file lands just under your number, and shows the quality it used.
What if quality alone can't reach my size?
The image is scaled down step by step until it fits, and the new dimensions are shown on the file. If a form also requires exact dimensions, resize to those first.
Will the photo look bad?
Below roughly 20 KB you'll see some softness. Use Compare on any finished file to check it against the original before you download.
Why did a file come back the same size?
Some images are already well compressed. With the Auto format, ImgKit keeps the original rather than hand you a bigger file.
Is there a limit on how many I can do?
No limit, no signup, no watermark. Your device does the work, and several files download together as a ZIP.
Which is better: lowering quality or reducing dimensions?
Quality first, because it keeps the picture the same size on screen. Dimensions are the stronger lever though — halving the width and height removes three quarters of the pixels — so for a tight limit like 20 KB, resize first and compress after.
Does compressing remove the location data?
Yes. The image is re-encoded from its pixels, so EXIF — including GPS — isn't carried over. If you only want to strip metadata and leave the image untouched, use the EXIF remover instead, which edits the file without re-encoding.
Why does the same size look fine on one photo and poor on another?
Detail is expensive to store. A portrait against a plain wall compresses far harder than a photo of foliage, a crowd or fine text, because there's less variation to encode. Busy images need either more kilobytes or fewer pixels.
