FAQ
Real questions. Straight answers.
Will my file be uploaded to the internet?
Image processing runs locally in your browser. Website resources and analytics use network connections. See How it works for the distinction and verification steps.
Can I compress a PNG to an exact KB size?
Close, but not always exact. PNG is lossless, so we reduce the dimensions to hit the target. For precise KB control, switch the output to JPG or WebP — those let us tune quality directly.
Why does the photo look blurry after compressing?
Smaller target = more detail removed. Try increasing the target KB slightly (e.g. 20 KB → 50 KB) or move the quality slider to the right. There's a sweet spot between size and sharpness.
Is there a file size limit?
No server-side limit — we never receive your file. The only limit is your device's memory. Very large files (20 MB+) may take a few seconds longer on older phones.
Does the background tool use AI?
No AI — it detects and replaces white or near-white pixels directly. Works best on clean studio backgrounds. Complex backgrounds or soft shadows may not be fully replaced.
Is this really free? What's the catch?
Completely free. No subscriptions, paywalled features, or watermarks. Optional treats support UploadReady — downloads never depend on a donation.
Can I compress a PDF here too?
Yes. Use the PDF tool and read the warning first: this mode turns pages into images and does not preserve searchable text, forms or digital signatures.
Does this work for signatures and ID photos?
You can set file size and dimensions for signature images and photos. Check the receiving form’s requirements. Background replacement works only with plain, light backgrounds.
