I built the photo side of Grabio because I kept hitting the same wall on my own iPhone: a photo that was the wrong shape for Instagram, the wrong format for a Windows PC, too heavy for an email, or carrying GPS data I didn’t want attached to it. None of that needed a paid app — iOS already has the tools to fix all of it, they’re just buried or missing a one-tap trigger. Grabio is that trigger: share a photo, tap one option, done, and the file never leaves your phone.
Below are the photo tools currently in Grabio, each with its own guide. Pick the one that matches what you’re stuck on.
Format & compatibility
- Convert HEIC to JPG — for when a site or app rejects your iPhone’s default photo format
- HEIC to JPG for WhatsApp — specifically for photos that break in WhatsApp on Android
- HEIC to JPG for Windows — for photos headed to a PC that won’t open HEIC
- Convert HEIC to PNG — when you need a lossless file for real editing work, not just compatibility
Size & shape
- Reduce a photo’s file size — for “attachment too large” errors and upload caps
- Crop a photo to a square — for a clean 1:1 Instagram grid
- Add a white background to a product photo — a square fit with no cropping, built for Etsy and Amazon listings
- Turn a Live Photo into a still JPG — when a Live Photo breaks an upload form
Privacy & cleanup
- Remove location (EXIF) from a photo — strip the hidden GPS data before you post
- Remove the background from a photo — cut out a subject for free, using Apple’s own subject-lift
All of these run with Apple’s native image actions directly on your iPhone — nothing is uploaded, and Grabio never sees the photo. If what you need isn’t in this list yet, it’s probably because there’s no honest on-device way to do it — check the PDF & document tools or video & audio tools pages for the rest of what Grabio does.
