How to add a border or film frame to a photo
Paint by Zaweba's decor filters add a plain border, round corners, a fuzzy border or a film frame to a photo in a few clicks, free and offline.

Borders and film frames come from the decor filters in Paint by Zaweba. There are four for framing: Add Border for a plain frame, Round Corners for softened edges, Fuzzy Border for a vignette that fades out, and Film Frame for the look of a negative strip. Open your photo, choose the filter and adjust it while you watch.
A frame finishes a picture, especially for printing, posting or putting in a card. The right one depends on the mood: a thin white border for clean gallery style, rounded corners for a friendly social post, a film frame for a vintage feel.
Choosing a frame
Add Border puts a solid edge round the picture. White suits most photos and keeps the attention on the picture; black can look strong on high contrast black and white work. Keep it thin for screens and a little thicker for prints that will be mounted.
Round Corners softens the edges, a style common on app screenshots and social posts. With a transparent background, save as PNG so the corners stay clear; as a JPEG they would be filled.
Fuzzy Border fades the edges into the background, which suits soft portraits, wedding photos and old fashioned looks.
Film Frame wraps the picture in the frame of a film negative. It pairs well with a little grain or a faded colour grade for a retro look.
Step by step with photo frames
Finish the photo first: crop, straighten and colour correct. A frame goes on last, because cropping afterwards would cut into it. Duplicate the photo layer and run the filter on the copy so the unframed version stays underneath. Pick the filter from the decor group, adjust the settings with the preview, and apply.
If you're printing, think about the paper. A border can be added by the Print window too, along with a caption, which saves editing the image itself for a one-off print.
The rest of the decor and photo filters
The same group has Coffee Stain and Fog for distressed or misty looks, and Bloom, Soft Glow and Gloom for light effects. A touch of Soft Glow with a Fuzzy Border makes a dreamy portrait; Gloom with Film Frame gives a moody vintage still. De-interlace and Broadcast Safe (NTSC/PAL) are there for frames grabbed from video.
Mistakes to avoid with photo frames
Heavy frames overpower photos. If people notice the frame before the picture, it's too much. A border that clashes with the photo's colours is distracting, so if you choose a colour, take it from the picture with the Eyedropper, or stick to white, black or grey.
Framing a photo that will be cropped elsewhere, such as a social site that cuts to a square, can lose the frame on two sides. Crop to the final shape before framing.
For many photos, use Batch with a saved action that applies the same frame, and every picture in a folder comes out matching. Batch keeps a batch-log.txt of each file it handled, so you can check nothing was missed, and the originals stay as they were if you send the results to a new folder.
