Rollphy Pro lifts the file limit and unlocks batch mode.
100KB is the most common image limit on the web: email attachment soft caps, online application forms, exam registration portals and legacy CMS upload fields all tend to draw the line here. This page compresses any JPG, PNG or WebP image under 100KB entirely in your browser — the file never touches a server.
Rollphy searches for the highest encoding quality that fits inside the limit and keeps the picture at full resolution whenever possible. A typical 12-megapixel photo drops under 100KB at reduced quality; a 1080p screenshot usually fits almost losslessly. If a huge source can’t fit at any quality, it is scaled down automatically and the final dimensions are shown.
Output is WebP everywhere the browser supports it (all browsers except Safari), which buys 25–35% more detail per kilobyte than JPEG. The result opens in every major app, portal and messaging platform.
Frequently asked questions
- How do I compress a JPEG to 100KB?
- Drop the file on this page — no settings needed. The compressor searches quality levels and picks the highest one under 100KB, then hands you the download.
- Does compressing to 100KB reduce the resolution?
- Not unless it has to. Full resolution is kept when the budget allows; only very large images get scaled down, and the tool tells you when that happens.
- Can I compress PNG to 100KB with transparency?
- PNG is lossless, so hitting a size target means re-encoding. Transparent areas become white in the output; if you need transparency kept, compress to a WebP-aware workflow or keep the PNG and resize first.
