Frequently Asked Questions

Does converting JPG to PNG improve quality?
PNG is lossless, but any compression loss already present in the JPG can't be recovered — only the format changes.
Can I upload multiple files?
Yes, you can drag and drop several JPG files at once.
Will my photo have a transparent background after converting to PNG?
No. JPG files don't store transparency, so the converted PNG is fully opaque — the format now supports transparency, but you'd need an image editor to actually remove the background.
Is my JPG uploaded anywhere during conversion?
No, the conversion runs locally in your browser using the Canvas API — your photo never leaves your device.
How large a JPG can I convert, and does the output keep the original resolution?
Files up to 100MB are supported, and the PNG is generated at the exact pixel dimensions of your original JPG — no resizing or cropping is applied.
