What does it mean to round the corners of an image?
Rounding the corners of an image means replacing its four sharp 90° corners with smooth curved ones, and exporting the result on a transparent background so the rounded shape sits cleanly on any layout. Upload a photo, choose how much curve you want, and the AI trims each corner to the same clean radius.
People add rounded corners to images for a softer, more modern look: profile pictures, app screenshots, product cards, blog thumbnails and social posts all read as more polished with a gentle curve. A rounded corner also removes the hard edge that can clash with a card or button behind it.
This round corners to images tool keeps your subject centered and sharp while it curves the edges, and gives you the file back as a transparent PNG so nothing shows a white box behind the curve. Prefer to change the shape or size too? Pair it with the AI image resizer to set exact dimensions first.

You can dial the corner radius from a subtle 14px curve to a full pill shape. Below, three real images generated on Pixazo are shown at three different radii — the same rounding you get on your own photo. Each frame is a genuine rounded corner, not a mock-up.
A soft, understated curve — ideal for cards, screenshots and thumbnails.
The everyday favourite — clearly rounded and friendly for social and web.
A bold lozenge look — great for hero banners and standout tiles.
To round an image's corners online, upload a JPG or PNG, choose a radius, and download the rounded image with a transparent background — three steps, no software. The tool hands your photo to Agent P with the rounding instruction already loaded.

Rounded corners help most on profile pictures, product and content cards, thumbnails, app screenshots and hero banners — anywhere a soft edge looks more modern than a hard 90° corner. Every image below is a real Pixazo render shown with a genuine rounded corner.
Cleaner store & catalog cards
Rounded product shots sit neatly inside cards and grids, matching modern UI corners.
Friendlier thumbnails
Soft corners make blog, recipe and menu thumbnails feel warmer and more tappable.
Polished hero banners
A gentle radius keeps wide covers and headers from feeling boxy on your page.
Making a round profile picture? A pill radius on a square crop becomes a circle — pair this with the AI image resizer for a perfect square, or start from a fresh face in the AI image generator.
Choose Subtle for cards and screenshots, Rounded for everyday social and web images, and Pill for bold banners or circular avatars — or type a custom note for a specific look.
| Preset | Approx. radius | Best for |
|---|---|---|
| Subtle | ~14px | UI cards, app screenshots, product tiles, table images |
| Rounded | ~34px | Social posts, blog thumbnails, web images, feature cards |
| Pill | ~90px+ | Hero banners, standout tiles, lozenge-style graphics |
| Circle | 50% of side | Profile pictures and avatars from a square crop |
| Custom | Your note | Round only the top corners, or match a brand radius |
- Transparent output. No white box behind the curve — the corner is truly cut.
- Even on all four. Every corner gets the same clean radius.
- Subject stays sharp. Only the edges change; the photo detail is untouched.
- Matches modern UI. Sits neatly inside rounded cards and buttons.
A sharp image with a little breathing room around the subject rounds best, because the curve trims the very edge of the frame. Run these quick checks before you round your corners.
- Leave edge margin. Keep important detail away from the corners the curve will trim.
- Start sharp. A crisp source keeps clean, anti-aliased curved edges.
- Know your radius. Decide Subtle, Rounded or Pill for a consistent set.
- Use PNG for graphics. Logos and UI keep clean edges as PNG.
- Match a square for circles. Crop to 1:1 first if you want a round avatar.
- Keep it transparent. Place the rounded PNG on any colour without a white box.
The tool accepts JPG or PNG files up to 5MB and returns a rounded image as a transparent PNG in seconds, free to try in any modern browser. AI rounding is quick and clean, but it works from the pixels you give it — here is the honest read.

This tool rounds an image's corners and exports a transparent PNG; it is not a full photo editor and does not change what is inside the photo. Here is an honest read on what to expect.
- It rounds corners, it doesn't retouch, remove objects, or change the subject — for edits use the AI image editor.
- Transparency needs PNG. A JPG can't hold a transparent corner, so the rounded file is saved as PNG.
- Detail near the edge that sits inside a large radius will be trimmed, so leave margin around the subject.
- It doesn't upscale. To enlarge first, use the AI image upscaler; to remove a background, use the background remover.
- You sign up for a free Pixazo account to use it; higher volume needs a paid plan.
Is the round-corners tool free to use?
Yes, it is free to try. You can round the corners of an image without paying. Higher volume and extra features come with Pixazo's paid plans, but you do not need a plan to try the tool.
Will the rounded image have a transparent background?
Yes. The rounded corners are cut out and the image is exported as a transparent PNG, so the curve sits cleanly on any colour or layout with no white box behind it.
How much can I round the corners?
Pick Subtle for a small curve, Rounded for an everyday look, or Pill for a bold lozenge. On a square image, a pill radius becomes a full circle for avatars. You can also type a custom note.
What image formats can I upload?
You can upload a JPG or PNG up to 5MB. The rounded result is returned as a PNG so it can keep the transparent corners.
Can I round only the top two corners?
Yes. Add a note in the prompt, for example "round only the top two corners," and Agent P rounds those corners while leaving the others square.
Can I make a round profile picture with this?
Yes. Start from a square crop and choose the pill radius to get a circle. For an exact square first, use the AI image resizer.
Do I need to install anything?
No. The tool runs in your browser on desktop and mobile. Upload, round, and download — nothing to install.
Do you store my uploaded image?
Your image is used to round its corners. For details on how long data is kept and how it is handled, see Pixazo's privacy policy.
