Are my images uploaded anywhere?

No. Conversion and resizing happen entirely in your browser using the Canvas API. Your files never leave your device.

What does Fit inside vs Fill & crop mean?

Fit inside scales the image down to fit within your Max width and Max height without cropping. Fill & crop scales and crops to exactly match the target area. Stretch forces exact dimensions, potentially distorting the image.

Can I convert many images at once?

Yes. Drop as many as you need, set your options, and click Convert / Resize All. You can download them individually or all together.

Does converting affect image quality?

For JPEG and WebP, quality depends on the slider — 80–90 is a good balance. PNG is lossless, so quality is preserved but file size stays large.

Which format should I use for a website?

WebP in most cases — it produces 25–35% smaller files than JPEG at the same quality and is supported in all modern browsers. Use JPEG as a fallback for very old browsers, or AVIF if you want the absolute smallest files with slightly less support.

Can I convert a PDF or HEIC file?

No. This tool handles raster image formats (JPG, PNG, WebP, GIF, BMP). For PDF pages, use our PDF to Image converter. For HEIC (iPhone photos), convert to JPG first using your device's export settings.
