Shrink an image to under 10KB as a JPG, right in your browser. Built for strict upload caps on signatures, ID photos and exam forms, with nothing uploaded anywhere.
Your files are processed in your browser, on your own device. Nothing is uploaded to a server.
It means re-encoding an ordinary image as a JPG that weighs less than 10,000 bytes. That is a tiny file, roughly the size of a short email with no attachment. Almost nobody picks 10KB because they enjoy small files. A portal, an exam form or an ID upload box set the cap, rejected the bigger file, and sent the person hunting for a tool like this one.
The output here is always JPG, because JPG squeezes an image harder than any other common format at this weight. This tool aims under the strict reading of the cap, below 10,000 bytes, so the file also passes a portal that counts 1 KB as 1,024 bytes and would turn away a file sitting at 10,200 bytes.
Signatures fit. A signature is dark ink on white paper, a few simple shapes, and it stays perfectly readable at 10KB. Flat graphics, simple logos and small ID thumbnails fit too. If the job is a signature for an exam form, the dedicated signature resizer also sets the exact pixel size and the minimum file size some portals demand.
A detailed photograph is a different story. Grass, faces, fabric and busy backgrounds carry a huge amount of tiny detail, and 10,000 bytes cannot hold that detail at a readable size. When a photo honestly cannot reach 10KB without being wrecked, this tool returns the smallest clean version it can make and says so on the result line. It never hands back a ruined picture in silence, and it never returns a file that is still over the cap without telling you.
Strict upload boxes are the usual reason. Some exam and government portals cap signature and photo uploads at 10KB. Older systems with slow connections behind them ask for tiny ID thumbnails. Forum avatars and email signature images on strict platforms live in the same range. The cap feels harsh, but it is rarely negotiable, so the file has to change instead. If your cap has a little more room, the 20KB compressor keeps noticeably more detail in the same kind of photo.
Two things happen on the way down. The pixel dimensions usually shrink, because a 4000 pixel wide phone photo cannot survive at this weight, and fine detail softens wherever the JPEG quality had to drop hard. Cropping the photo to the part that matters before you compress gives the tool far less to carry, and the result looks better for it.
One gain comes free. Re-encoding strips the metadata a phone hides inside its photos, including the location data most people would rather not hand to a random portal. And if your image is already under 10KB, the tool leaves it exactly as it is. No pointless re-encode, no quality lost for nothing.
The compression runs in your browser, on your own machine. Nothing is uploaded, nothing is stored, and nobody at ToolPeko ever sees your photo or your signature. Close the tab and the work is gone, which is how a tool that handles ID uploads ought to behave. Every tool in the image converters collection works the same way.
By giving up size in two places. The tool first lowers the JPEG quality, then shrinks the pixel dimensions if the file is still too heavy. The finished photo is small on screen, which is fine for a thumbnail or an ID slot, and that is the trade a 10KB cap forces.
Yes. Ink on white paper is one of the easiest images to compress, because there is so little detail to store. Signatures, stamps and simple line drawings come through 10KB clean and readable.
Some photos carry too much detail for 10,000 bytes at any readable size. Rather than destroy the picture, the tool returns the smallest clean version it can make and tells you on the result line. Cropping the photo tighter before compressing usually closes the gap.
Nothing. A file that already fits is returned untouched, pixel for pixel. There is no reason to re-encode a file that already passes.
Yes. Drop in a batch and each image is squeezed to the same target. The finished files come back together in one ZIP, each with its final size shown.
Yes. Phone photos carry hidden metadata, and GPS location is part of it. Saving the photo again as a fresh JPG leaves that metadata behind, which is a quiet privacy win on top of the smaller file.
Same rules as this one: free, in your browser, with nothing uploaded.
