Frequently asked questions
How do I compress an image to exactly 40KB?
Open Compress Image with the 40KB preset, drop your JPG/PNG/WebP, and download. Target mode adjusts quality (and scales if needed) until the file is at or under 40KB — all on your device.
Should I resize before compressing?
Yes if the portal also sets pixel dimensions. Resize to the required width/height first, then compress to the KB cap. Fewer pixels make tight limits easier without muddy faces.
Is my photo uploaded?
No. TryQuickImg compresses in your browser. After the page loads you can go offline and still finish — nothing is posted to a remote API.
