Not every platform accepts every image format, and file size can vary significantly between PNG, JPG, and the newer WebP format. This tool re-encodes any image you upload into your chosen output format directly in the browser using the canvas API.
PNG preserves transparency and sharp edges well, JPG is generally smaller for photos but has no transparency, and WebP typically offers the best compression of the three for similar visual quality.
Since conversion happens locally, your original file is never uploaded to a server.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this conversion or calculation often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from search result to working tool in a couple of seconds.
Because the calculation or conversion happens instantly as you type, you can experiment freely and see how changing one value affects the result.
The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.

Frequently asked questions
Which format should I pick?
Use PNG for graphics with transparency or sharp lines, JPG for photos where small file size matters more than lossless quality, and WebP when the platform supports it for the best balance of both.
Will converting to JPG lose transparency?
Yes, JPG doesn't support transparency — any transparent areas will be filled with white or black depending on the browser.
