How it works
- Drop your file (JPG / PNG / PDF) into the box below — nothing is uploaded anywhere.
- The preset is pre-loaded with the 10 KB – 20 KB target; adjust the boxes if your portal differs.
- Hit Compress — the engine binary-searches ≈ 8 encode passes in under a second.
- Download the file. If the portal has a minimum-KB rule, padding bytes keep it safely inside the range.
Frequently asked questions
Is this image compressor free?
Yes — 100% free with no watermark, no signup and no daily limit. All processing happens inside your own browser via canvas/JPEG encoding, so there are no server costs to pass on to you.
What are the exact file requirements?
Drop your file and the output will land 10 KB – 20 KB. You can change the target before compressing if your portal uses a different limit.
My file compresses below 10 KB and the portal rejects "file too small". What now?
Tick "Enforce range" (enabled by default here). The engine adds invisible metadata (JPEG comment segments) so the file lands safely inside 10 KB – 20 KB — the visible image quality and pixels are 100% unchanged.
Is my photo or document uploaded to a server?
No. Unlike ilovepdf, tinypdf or similar tools, this page has no upload at all — compression runs on your device with JavaScript. It even works offline once the page has loaded.
