How to Add a Frame to a Photo Online (Free)

By Ismail Farooq · 3 November 2026 · 6 min read

To add a frame to a photo online, open a free frame tool, drop in your picture, pick a frame style and download the result. The free Photo Frames tool offers a Polaroid, a film strip, a gallery mat, a rounded card, a wood frame and a plain border, with an optional caption, and draws the frame in your browser. There is no sign-up and no watermark, and your photo is never uploaded.

How to add a frame to a photo in four steps

1. Open the tool and add the photo. Open Photo Frames and drop in your photo. The first preview appears straight away.
2. Choose the Frame. The preview updates each time you change it, so you can try all six in a few seconds.
3. Set the Frame size, and a Colour or Caption. Colour works on the plain border and the rounded card; Caption works on the Polaroid and the gallery mat.
4. Pick the format under Save as and download. JPG is the default and right for most photos. PNG keeps every pixel, and WebP makes the smallest file for a website.

Which frame to choose

We ran one 4000 × 3000 px test landscape through every frame at the default frame size. These are the sizes the tool downloaded:

The file sizes stayed close to the original's 253 KB for most frames (190 to 276 KB as JPG). The wood frame was the exception at 697 KB, because its grain is fine detail that JPG cannot squeeze as well as a flat colour.

How big the frame will be

The Frame size slider runs from 2 to 20, and it is a percentage of the photo's shorter side. The default is 6. On our 3000 px tall test image that made a 180 px border, so the plain border added 360 px to each dimension. At 2 the picture grew to 4120 × 3120 px, and at 20 to 5200 × 4200 px.

Because it is a percentage, the frame looks the same on a small phone photo and a large camera file. A border is never thinner than 4 px, so even a tiny image gets a visible edge. The other frames scale the same base width:

• Polaroid: the sides and top use the base width, and the bottom is 3.6 times as deep, which leaves room for the caption.
• Film strip: the black bands at the top and bottom are 1.7 times the base width, and the sides are half of it.
• Gallery mat: a dark frame of about half the base width, then a mat of 1.6 times it. A caption adds a strip under the photo.
• Wood frame: 1.2 times the base width on every side.

The photo itself is not resized. It is drawn at its own pixel size, so a frame never makes it softer.

How to make a Polaroid-style photo

Choose Polaroid, type a short caption and download. Short captions work best: a place and a month, a name, or a date, such as Hilltop sunset in our example. The tool writes it centred in the deep bottom edge and shrinks it to fit if it is too long; anything past 80 characters is cut.

The caption uses a handwriting font that your device already has, such as Segoe Print on Windows or Bradley Hand on a Mac, so the lettering looks a little different from one computer or phone to the next. If you want an exact font, leave the caption empty and add the words afterwards with Add Text to Image.

For reference, real Polaroid i-Type film is 3.483 × 4.233 inches, with a picture area of about 3.1 inches square, according to Polaroid's support pages. That makes the real bottom edge deeper than ours. If you want the classic square look as well, crop the photo to 1:1 with the Image Cropper before you frame it.

How to post a framed photo on Instagram

A frame changes the photo's shape. Our 4:3 landscape came out at 4360 × 3828 px as a Polaroid, which is close to square, and a portrait photo grows taller still. Instagram accepts feed photos between 1.91:1 and 4:5 and crops anything outside that. Two simple fixes:

• Fit it: put the framed picture through No Crop and choose 4:5. It adds a background around the frame instead of cutting into it. See how to post a full picture on Instagram without cropping.
• Size it: resize the result to 1080 px wide with the Image Resizer, which is all Instagram shows and keeps the upload quick.

For the other networks, our social media image sizes guide lists the current shapes.

How to print a framed photo

Photo labs print fixed shapes, such as 4 × 6 inches, which is 3:2. A framed picture is rarely exactly 3:2, so the lab either crops into your frame or adds a white edge of its own. To avoid both:

1. Frame the photo.
2. Open the result in Canvas & Border and expand the canvas to the print shape in the frame's own colour, or crop it to 3:2 with the Image Cropper if the frame has room to spare.
3. Check the pixels against the print size in our DPI guide. A 4 × 6 print at 300 DPI needs 1800 × 1200 px.

Save as PNG or a high-quality JPG for print. If the picture is going on a holiday card, our holiday photo card guide covers layouts and bleed.

When to use a different tool

The rounded card fills its corners with the colour you choose rather than leaving them transparent, so pick the colour of the page the picture will sit on.
