If even low quality is too big, it reduces the dimensions step by step and tries again. Sizes count 1 KB as 1,000 bytes, slightly stricter than 1,024, so the file fits either way. The new file carries no EXIF data (no location or camera details).

Crop first, then let the tool do the rest. Step 1 Keep "Under 20 KB" selected, and add exact dimensions if the form specifies them. Step 2 Drop, paste or choose your signature scan or photo. Step 3 Check that the final size is under 20 KB, then download it. ## Tips for a Crisp File Under 20 KB 20 KB is small. A little preparation keeps signatures sharp and faces recognisable. ### Crop the Signature Tightly Cut away the blank paper around your signature. Empty space still costs bytes. ### Plain Paper, Even Light Dark ink on clean white paper, captured in even light, compresses into a small, crisp file. ### Keep Dimensions Modest If the form gives dimensions, set them under Exact size. Otherwise the tool shrinks the image only as far as it must. ## Safe for Your Signature A signature is sensitive. This tool never sends it to a server. ### Processed on Your Device Your signature and photo are compressed in your browser and never uploaded. ### Best Quality That Fits The highest quality under 20 KB is picked automatically, with every attempt listed if you want to check. ### Signature and Photo Together Add both files at once and download them in one zip. ## Try DragBin Today Pair private, in-browser file tools with zero-knowledge, quantum-resistant cloud storage. 5GB free, forever.

A small head-and-shoulders photo fits in 20 KB as a JPG. A full-resolution phone photo can't, so the tool reduces its width and height until it fits and shows you the final dimensions. ### How do I get my signature under 20 KB? Sign in dark ink on plain white paper, photograph or scan it in even light, and crop away the blank paper around it. Then drop it here with "Under 20 KB" selected. Signatures compress very well, so the result usually stays crisp. ### Why does my signature look blurry or grey? Very low quality smears thin lines. Crop tighter and keep the image small, so more of the 20 KB goes to the strokes themselves. Brighter, even lighting while photographing the signature helps most. ### Can the file end up over 20 KB? No. The tool only offers files at or under 20,000 bytes, which also passes on sites that count 1 KB as 1,024 bytes. If an image can't get that small, it's marked as failed and the smallest size reached is shown. ### Are my signature and photo uploaded? No. Everything is processed in your browser and stays on your device. For HEIC photos outside Safari, or WebP output in Safari, the page downloads a decoder or encoder from dragbin.com; your files are never sent anywhere.
