Why warn about JPG and transparency?

JPEG has no alpha channel, so transparent corners would fill with a solid colour. Choose PNG or WebP to keep transparency.

Can each corner differ?

Yes. Disable linked corners to set top-left, top-right, bottom-right, and bottom-left independently.

Is processing private?

Yes. Rounding is applied on a local canvas.

Is this image tool free to use?

Yes. You can use this tool directly in your browser for free, without account creation or hidden upload limits.

Do my files leave my device?

No. Processing happens locally in your browser, so your files stay on your device and are not uploaded to our servers.

Will the output match the preview?

Yes. The preview is scaled for display, but exports use the original image resolution and the same processing settings you chose.

What is Rounded Corners?

Adjust unified or per-corner radii, pick transparent/white/custom backgrounds, and use presets from slight rounding to circle/pill. Transparency exports as PNG or WebP.

Trust and privacy are built into the workflow. No files leave your device during processing, and there is no account setup required. That makes Rounded Corners suitable for personal photos, client assets, product images, and everyday creative work.

How to use Rounded Corners

Upload or drag your image into the tool above.
Adjust the editing controls until the live preview looks right.
Choose an output format (and quality when relevant).
Download the edited image — processing stays on your device.

Tip: preview at a comfortable zoom, then export once you are happy — repeating lossy saves can add compression artifacts.

Key benefits of Rounded Corners

JPG cannot store transparency — switch to PNG/WebP for clear corners
Circle/pill preset uses half the shorter side as radius
Per-corner mode is useful for card-style crops
Original dimensions are preserved

Privacy note: no files leave your device. All edit steps run locally in your browser.

Common use cases

Use this for avatars, product cards, and UI mockups. Convert to PNG first with JPG to PNG if you need a transparent result from a JPEG photo.

After you finish, continue with related PictureConvert tools if you need another conversion, compression pass, crop, or metadata step — all without leaving the browser.
