Open your picture and it is compressed to less than 10 KB, at or under the cap, automatically. The tool finds the highest quality that stays below the cap and scales the dimensions down only when a large photo cannot fit otherwise. The size card shows the original size, the new size and the exact saving, and the preview is the actually compressed image, so you can judge legibility before you download.
A 10 KB cap is the classic signature field: exam registrations, scholarship and recruitment portals, bank and insurance forms routinely want a scanned signature between 4 and 10 KB next to a photo that gets 20 to 50 KB. Drop the scan of your signature here and download a JPG that goes through the first time. Because a signature is mostly white paper, it compresses far better than a photo and normally keeps its full dimensions under the cap.
A face photo also fits, at roughly 200 to 350 pixels on the long side. That is enough for a passport style photo field or a small profile picture, and the preview shows exactly how the compressed result looks, so there are no surprises after upload.
If your form names another number, compress image to 5 KB, 15 KB, 20 KB or 50 KB instead; every page opens with its target set, and the presets carry the picture across. Any custom cap can be typed into the target box, the Quality button on this page swaps the target for a slider, and the main Compress Image tool opens in that mode. The full compressor collection shows every cap side by side.
Your signature or photo never leaves your device: compression happens entirely in your browser, with no upload, no queue and no account. For identity documents that is not just faster, it is safer.
Scan or photograph the signature on white paper, crop it close, then open it here. The tool automatically finds the highest quality that fits under 10 KB and the preview shows the result before you download it.
Open the photo and the tool compresses it under 10 KB by itself, reducing the dimensions just enough when the picture is large. The download is a JPG unless you pick WebP or PNG on the download button.
Roughly 200 to 350 pixels on the long side for a normal face photo. Signatures and drawings on white fit at much larger dimensions because most of the image is flat.
No. Everything runs in your browser and the file saves straight back to your device. No server ever sees your signature or photo.
