Large photos slow down web pages, fill up storage, and take longer to share. This tool compresses JPG and PNG images directly in your browser using the canvas API, re-encoding the image at an adjustable quality level without ever uploading your file anywhere.
Drag the quality slider to trade off file size against visual fidelity, and compare the original and compressed previews side by side before downloading.
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.
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.
This tool avoids unnecessary steps like account creation or email verification, since the underlying task itself is simple enough not to need them.
Because the whole process happens client-side, there's no waiting on a slow server response or worrying about a service outage affecting your work.
Frequently asked questions
Is my image uploaded to a server?
No, compression happens entirely client-side using your browser's canvas rendering — the file never leaves your device.
Does this work for PNG transparency?
Re-encoding a PNG with transparency as JPEG will lose transparency; for images with transparent backgrounds, keep the output format as PNG for best results.
