Compress JPEG to 50KB, 100KB or 200KB for portal uploads
Application portals, job sites and government forms reject JPEGs above strict limits — often 50KB or 100KB. Instead of repeatedly guessing a quality value, switch to Target Size mode and enter the limit. The tool re-encodes through a quality binary search and stops at the largest file that still fits, so your photo keeps the maximum detail the limit allows.
How JPEG quality levels actually work
JPEG shrinks files by discarding fine detail the human eye barely registers. Quality 70–85 is the sweet spot where photos look unchanged at normal sizes; below 50, blocky artifacts appear around edges and text. The live preview here shows the result at your chosen setting before you download, so nothing is left to chance.
Already as small as it gets? Convert to WebP
When a JPEG refuses to shrink further without falling apart, the format itself is the bottleneck. Re-encoding the same photo as WebP typically cuts another 25–35% at identical visual quality. If your destination accepts WebP, use our JPG to WebP converter and keep the quality you would otherwise lose.
Frequently asked questions
Does compressing a JPEG again and again ruin it?
Yes — each re-save discards a little more detail (generation loss). Always compress from your original file rather than from an already-compressed copy.
Can I compress a JPEG to an exact KB size?
Yes. Target Size mode accepts any KB value and automatically finds the highest quality that fits under it.
Is there a maximum file size?
Files over 25MB or beyond 4096×4096 pixels are automatically downscaled first for reliable in-browser processing — you are warned before it happens.
Is my photo uploaded anywhere?
No. Compression runs entirely in your browser; the file never touches a server.
