Compress JPEG to 50KB

This compresses a JPEG using the quality slider rather than hunting for one exact byte count — start at a preset tuned to land most everyday phone photos near 50KB, watch the live before/after size, and nudge the slider until the number you want shows up. Nothing uploads; the JPEG is re-encoded on your own device.

Questions people ask

How do I compress a JPEG to exactly 50KB?

This page compresses by quality level and shows you the resulting file size live, so drag the slider down until the number reads 50KB or below. If you need a byte-exact 50KB every time with no manual adjustment, the exact-KB photo tool (linked below) hits that target automatically instead.

Will compressing to 50KB make my photo blurry?

A phone photo usually still looks reasonable around 50KB because most of what gets discarded is fine texture and noise the eye barely registers at that resolution. A busy, detailed image will show more softening than a simple one — check the live preview before downloading.

Are my images uploaded anywhere?

No. The conversion runs in your browser using the Canvas API, and this site has no upload endpoint. Once the page has loaded you can go offline and it still works.

Is there a file size or batch limit?

You can convert 25 images at a time, and file size is limited only by your device's memory. Because there is no server involved, there is no daily cap and no account to create.

Does converting reduce the image quality?

Converting to PNG is lossless. Converting to JPG or WebP re-compresses the picture, so the quality slider controls the trade-off — 82% is a good default that most people cannot distinguish from the original.
