Resize an image to exact pixels or a percentage, on your phone
iEdit resizes a photo on your iPhone, iPad or Android device to an exact width and height, a percentage, or a preset such as 1080×1920 for stories. Lanczos resampling keeps edges clean, the colour profile and EXIF details are kept, and the image never leaves your device.
Overview
Type a width and height in pixels with the aspect ratio locked, enter a percentage from 1 to 200, or tap a preset: 1080×1080 and 1080×1350 for posts, 1080×1920 and 1920×1080 for stories and video covers, 1280×720 and 3840×2160 for HD and 4K. Choose Fit to keep the whole picture, Fill to crop to the exact size, or Stretch. The result is saved as a JPEG at 95% quality with its EXIF details, or as a lossless PNG.
Scaling uses Lanczos resampling, the method professional tools use, so edges stay clean and fine texture is not smeared. The photo's colour profile, whether Display P3 from an iPhone or Adobe RGB from a camera, is carried into the result, and HEIC and WebP files go in as readily as JPEG and PNG. Images up to 20,000 pixels on an edge and 100 megapixels are accepted, and iEdit warns you that enlarging adds pixels, not detail.
Use it to fit a profile picture into a square, bring a 48-megapixel photo down to a sensible size for a form upload, or match the exact dimensions a website asks for. Resizing happens on your device, so a photo of an ID card or a contract is never sent anywhere, and the tool works with no connection at all.
Why people use it
- 01
Exact pixels or percentage
Lock the aspect ratio and type one side, or scale the whole image from 1% to 200%.
- 02
Presets for social and 4K
Six common sizes from 1080×1080 to 3840×2160 are one tap away.
- 03
Lanczos quality, profile kept
Edges stay clean and colours stay true, because the colour profile travels with the image.

Frequently asked questions
Does resizing a photo in iEdit lower its quality?
Shrinking a photo discards pixels by design, but Lanczos resampling keeps edges clean and JPEG output is saved at 95% quality, so the loss is hard to see. Enlarging adds pixels rather than detail, and iEdit says so before you save. Choose PNG when you need a lossless result.
Is the image resizer free, and can I save the result to my photos?
Resizing is free, and every result is saved to My files inside iEdit at no cost. Saving the resized image to your photo library or to Files, or sharing it with another app, is part of iEdit Premium, an optional monthly subscription with a 3-day free trial.
Are my photos uploaded when I resize them?
No. iEdit resizes images entirely on your iPhone, iPad or Android device. Nothing is sent to a server, no account is needed, the tool works offline, and your original photo is left untouched; the resized copy is saved as a new file in My files.
