Frequently asked questions
What is JPG?
JPG (JPEG) is the most widely supported photo format. It uses lossy compression to keep photos small, and it opens on virtually every device, browser and app.
What is PNG?
PNG is a lossless image format that supports transparency. It is ideal for screenshots, logos and graphics with sharp edges, but photos saved as PNG are much larger than JPG.
What's the difference between JPG and PNG?
JPG uses lossy compression to keep files small, while PNG is lossless and keeps every pixel exactly, at the cost of larger files. PNG supports transparent backgrounds; JPG doesn't, so transparent areas are filled with a background color when converting.
Is it safe to convert my files here?
Yes. The conversion runs inside your browser, so your files are never uploaded to a server. Close the tab and nothing remains.
Are there any limits?
It's free with no sign-up. Each file can be up to 100 MB, and you can convert up to 5 files at once.
