Compress Image to 50 KB

Online forms often set a strict size limit for photos and signatures. Choose your image above and it is compressed to 50 KB or less automatically. The tool starts at the highest quality and lowers it step by step until the file fits; if the photo is very large, it is also reduced in pixel size, which keeps it clearer than squeezing a huge image into a tiny file.

• Check other requirements too. Many forms also ask for specific dimensions (for example 200 × 230 pixels) or a format. Use the converter to change the format, and the Resize option here to set the size.
• Crop first. A tight crop of the face or signature keeps more detail within the same file size.
• Scan signatures in good light on white paper: a clean background compresses far smaller than a grey, shadowed one.

Use Compare on any image to drag between the original and the compressed version before you download.

• Resize large photos. A 12-megapixel phone photo is about 4000 pixels wide; a website rarely shows images wider than 1920. Setting a maximum size is often the single biggest saving.
• Use the right format. Photos belong in JPG or WebP; screenshots, logos and graphics with flat colours in PNG. WebP is typically 25–35% smaller than JPG and works in all current browsers.
• Compress from the original. Each round of lossy compression loses a little more detail.

Compression runs in your browser using WebAssembly versions of MozJPEG, libwebp and OxiPNG, the codecs behind Google’s Squoosh (licences). Your images are never uploaded. Compressed files are saved without EXIF metadata, so camera details and GPS location are not shared.

• Saving photos as PNG

  A photo saved as PNG is often five to ten times the size of a good JPG with no visible benefit. Choose JPG or WebP under "Save as".

• Compressing a screenshot as JPG

  Text and sharp edges in screenshots blur and ring as JPG. Keep screenshots as PNG; the palette compression here shrinks them just as much.

• Squeezing a huge photo into a tiny file

  A 4000-pixel photo at 50 KB looks blocky. Reduce the pixel size first (the File size mode does this for you) and the result stays clear.
