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 is WEBP?
WebP is a modern image format developed by Google. It produces smaller files than JPG and PNG at similar quality and supports transparency, but some older apps and editors cannot open it.
Will I lose quality?
Making an image smaller keeps it sharp. Making it larger than the original can look blurry because detail can't be added.
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.
