Image Converter is an iPhone toolkit for changing how a photo looks and what shape it is in. It converts between six common formats, shrinks file size, fixes rotation, crops and resizes, and stitches multiple photos into a single image. Everything runs on your phone.
Six formats, one tap each way
Move freely between JPG, JPEG, PNG, WebP, BMP and TIFF. Tap a format chip to pick the target, conversion runs locally and keeps the original resolution, so output quality matches the source. HEIC photos from the iPhone camera roll are recognized on import and exported as one of those six formats.
Compression you can see
A quality slider runs from 1 to 99. Nine preset chips (10/20/30/40/50/60/70/80/90) cover the common cases. The original and compressed file sizes sit side by side while you drag, so you can confirm the savings before saving. For everyday sharing, 60 to 80 is the usual sweet spot; 90 and above is for archival copies or prints.
Rotate, flip, and the EXIF fix
Rotate a single image in 90-degree steps left or right, or flip it horizontally or vertically. EXIF orientation is detected and the pixels are rotated for you before export, so the saved file opens the right way up everywhere, not just in apps that read the EXIF tag.
Crop to any ratio
Trim edges with the built-in crop tool. Lock to a fixed ratio like 1:1, 4:3 or 16:9, or drag the frame freely. Resize by pixel width and height, optionally keeping the original aspect ratio to avoid distortion.
Stitch up to 20 photos
Combine up to 20 photos into one image. Vertical mode produces a tall strip for chat screenshots. Horizontal mode lays them out side by side. A 3x3 grid makes a gallery. Drag to reorder before exporting.
Everything on your phone
Format conversion, compression, rotation, cropping, resizing, and stitching run locally. Files never leave your device, and your conversion history lives only in a local database on your phone.
Free and Pro
All six tools are free to use. Free users see a short rewarded ad before each conversion. Pro subscribers convert without ads. Pro is sold as an auto-renewing subscription through the App Store.
