Border & Rounded Corners

Border & Rounded Corners puts a picture on a background and dresses it up: space around it (padding), a coloured border, rounded corners and a soft drop shadow. It is the quick way to make screenshots look tidy in a blog post, give product shots a matching frame, turn a photo into an instant-photo print with a deep bottom edge, or round the corners of an avatar.

It also solves the Instagram problem. Choose “Square 1:1” or “Portrait 4:5” under Shape and the picture is padded out to that shape instead of being cropped, so nothing gets cut off. Other shapes include a 9:16 story, 16:9 and any custom ratio you type.

Sizes can be in pixels, or in a percentage of each picture’s shorter side, which is the default. With percentages, a batch of mixed sizes gets frames that look the same on every image. Everything is drawn by your own browser: the pictures are not uploaded anywhere, and there is no sign-up or watermark.

1. Press “Choose files”, drag pictures onto the box, or paste one. You can add up to 50.
2. Tap a quick style such as “Soft card”, “Instant photo” or “Instagram square”, or set Padding, Border, Corners and Shadow yourself. The preview updates as you type.
3. Under Background, pick a colour, or “See-through” for a transparent background.
4. Optional: choose a Shape to pad every picture to a fixed ratio, and change “Save as”.
5. Press “Add border” (or “Add border to 8 images”), then download each picture or all of them as one ZIP.

• Padding equal on all sides or set per side (top, right, bottom, left).
• Border with any width and colour, drawn as a ring so see-through parts of a picture stay see-through.
• Rounded corners from a gentle curve to a full circle or pill shape; the picture and border curve together.
• Drop shadow with its own offset across and down, blur, colour and strength. The padding grows automatically where needed so the shadow is never cut off.
• Background in any colour, or see-through (saved as PNG, because JPG can’t hold transparency).
• Pad to a shape: square 1:1, portrait 4:5, story 9:16, landscape 1.91:1, 16:9, 3:2 or a custom ratio.
• Five quick styles, plus sizes in pixels or as a percentage of the shorter side so mixed batches match.
• Batch of up to 50 images with a live preview of any picture you tap; download one by one or as a ZIP.

• For a crisp look on social media, use a light background, a little padding and a soft shadow with low strength: around 25–35% is plenty.
• For a round profile picture, crop it square first, then set the corner rounding to 50% with no padding and a see-through background.
• When you switch between pixels and percent, the numbers are converted for the picture in the preview, so the frame doesn’t jump.
• With “Same as original”, JPG stays JPG and PNG stays PNG; any see-through background switches the file to PNG.
• Big frames add pixels. If the result needs to be under a size limit, run it through Compress Image afterwards.
