Frequently Asked Questions
What does this tool do?
It converts images between formats (e.g. PNG to JPEG, WebP to PNG) and lets you resize by scale or max edge pixels — all in your browser, with no server upload.
Which formats are supported?
Input: JPG, PNG, WebP, GIF, BMP, AVIF, ICO, and SVG. Output: JPEG, PNG, WebP, GIF (single frame), BMP, and AVIF. ICO is supported as input only.
Are my images uploaded?
No. Conversion runs entirely in your browser. Your files never leave your device.
Can I convert animated GIFs?
Animated GIFs are converted using the first frame only. For animated output, use a dedicated GIF tool.
Will resizing reduce image quality?
This tool uses high-quality stepped scaling (gradual downscale or upscale) to keep images as sharp as possible. For shrinking photos, max-edge mode is often the best choice.
