Quality, privacy, and download control
Local only: images never leave your device because processing happens directly in the browser.
Batch friendly: select multiple files once and export everything together when the previews look right.
Compression aware: for smaller targets we may convert PNG, GIF, or BMP files to JPEG to achieve stronger size reduction.
FAQ
Can I resize multiple images at once?
Yes. Choose multiple files, process them together, and then download each file or export a ZIP.
Will my images be uploaded to a server?
No. Everything runs on-device in your browser for better privacy and faster previews.
Can I avoid enlarging small images?
Yes. In pixel mode, enable the no-upscale option and we will keep smaller images at their original size.
Will the target KB size be exact?
We aim to get as close as possible. The final size can vary slightly depending on image content and format limits.
