How it works
Choose one or more images and FileKivo finds the highest JPEG quality that fits under 50 KB. If even low quality is too large, it gradually reduces the pixel dimensions until the file fits. The result card shows the final size, dimensions and quality so you can see exactly what changed. Here 1 KB means 1,000 bytes; if a form uses 1,024 bytes per KB, your file has a little extra room.
Good for
A 50 KB target is common for online forms that cap photos at 50 KB. Before compressing, check whether the form also has a minimum width and height in pixels: shrinking a photo to fit a size limit can push it below a minimum dimension. You can set a "largest side" value to control the dimensions yourself.
Getting the best result
- Crop away empty background first with Resize an image; fewer pixels leave more room for detail.
- Photos of paper documents compress better when the page fills the frame and the lighting is even.
- Always open the downloaded copy and zoom in to check faces and small text are still clear.
Private and free
Compression uses your browser's built-in image encoder. Nothing is uploaded, there is no watermark, and you can compress up to 20 images at a time. Need a different size? Try 20 KB, 50 KB, 100 KB, 200 KB or any custom limit.
Questions
- Will the image be exactly 50 KB?
- It will be under 50 KB, as close as the tool can get while keeping the best quality.
- Can I keep PNG transparency?
- Output is JPG, which uses a white background. Use the main compressor if you need WebP.
- Is my photo uploaded?
- No. Everything runs in your browser.
