White Border 17+

Used this app constantly to size my photos to send to friends and also to post on socials.
Recently had it auto update and now it crashes every single time I try and save more than 5 photos and it also changed my border size so now my photos are no longer consistent.
Disappointed

It may be early to say this after one day’s use, but White Border looks very, very much like the ideal no crop app for Instagram posts. The App Store is absolutely silly with these, but you’ve likely discovered that they have big flaws: they tend to be slow and clunky, forcing a long wait after exporting each photo. Many are also bloated with photo editing features that belong in a different app. White Borders is perfect for a heavy posting workflow: it’s fast, has few unnecessary options, and even lets you mass select up to 10 photos at once to add borders with one click. Makes doing a 10-image post with mixed orientations a two-minute process instead of ten. And it costs three bucks to remove ads for good! Tao Zhang is a superstar.

UPDATE: After using the app for a while, it absolutely does bear out the strong first impression — it’s simple, easy, and quick to do exactly what it’s supposed to. Blows any other app I’ve tried for this purpose out of the water.

The one flaw I’d point out is that if you have photos in a lot of albums it’s hard to find the one you want — they seem to be listed in a random order. I’d appreciate search, or at least alphabetic order, or even better support for the folder system so you can organize them.

I’m an old-school photographer, one who’s not at all tech-savvy, and I found this app a breeze to use (after having tried many others without success).
It adds a white border around a photograph—either all the way around *or only on the two sides*.
My vertical photos, the ones that don’t quite have the aspect ratio required by Instagram, for instance, now post perfectly! No cropping required.
A simple-without-being-simplistic and elegant solution. Highly recommended!
