Frequently asked questions
Are my images uploaded anywhere?
No. Everything runs in your browser using its built-in image engine. Your files never leave your device — you can even use QuickImage offline once the page has loaded.
How do I compress an image to under 100 KB?
Choose "Target size" in the Compression panel, enter 100 KB and press Process. QuickImage automatically searches for the best quality that fits, and scales the image down if needed.
What's the difference between JPG, PNG and WebP?
JPG is the universal choice for photos. PNG is lossless and supports transparency but makes big files. WebP is a modern format that's typically 25–35% smaller than JPG at the same visual quality — great for the web.
Does it work with transparent PNGs?
Yes. Transparency is preserved when exporting to PNG or WebP. Exporting to JPG (which doesn't support transparency) fills the background with white.
Is there a file size or count limit?
Free mode processes one image at a time, of any size your browser can open. Premium unlocks unlimited batch processing with a single ZIP download.
Is the quality slider used for PNG?
No — PNG is lossless, so quality doesn't apply. To make a PNG dramatically smaller, convert it to WebP or JPG, or resize it.
