Frequently asked questions
Which image format should I use?
JPG for photos, PNG for screenshots and logos with transparency, WebP or AVIF for the smallest files on websites, ICO for favicons and Windows icons, and PDF for documents you want to send or print.
Does converting reduce image quality?
Converting to PNG, TIFF or BMP keeps every pixel. JPG, WebP and AVIF use compression; at 90% quality the difference is very hard to see.
How do I open iPhone HEIC photos on Windows?
Convert them with HEIC to JPG. The JPG files open everywhere, and you can convert many HEIC photos at once.
Can I convert several images at the same time?
Yes. Every converter accepts many files, and the Bulk Image Converter handles whole folders.
Are my files uploaded to a server?
No. The conversion runs in your browser, so your images never leave your device.
