FAQ
Will compression reduce image quality?
Compression lowers quality slightly, but you control the level (1-100). Above 80 the difference is usually invisible. I typically use 85 — file size halves with no visible change.
Which formats are supported?
JPEG/JPG, PNG and WebP. Any input format can be converted to any output format in the same step.
Are my images uploaded to a server?
No. All processing happens inside your browser. Images never leave your device — close the tab and they are gone.
Can I compress multiple images at once?
Yes. Select multiple images to compress them in batch, then download them all as a ZIP archive.
