HEIC Resizer
Resize
Enter one value and the other follows automatically while locked.
Saves the edited image at its current dimensions. JPG, PNG, and WebP keep their format; other supported inputs download as JPG. Check the downloaded file for final quality.
Your images are processed locally in your browser and never uploaded to any server.
Resize one HEIC photo at a time without installing software. The HEIC decoder loads in your browser on demand: choose dimensions or a percentage, click Apply resize, and download the result as JPG. Aspect-ratio lock and output quality control are included, but there is no format selector. Nothing is uploaded.

- Add one .heic photo.
- Enter a width or height with the aspect lock on, or choose a percentage. Click Apply resize.
- Adjust output quality and check the resized preview.
- Click Download to save the photo as JPG. Repeat separately for another HEIC file.
Frequently asked questions
Can the output stay HEIC?
No. This resizer automatically saves HEIC input as JPG. It does not offer HEIC, PNG or WebP output choices. Use a separate converter if you need a different output format.
What size should iPhone photos be?
Choose dimensions for the destination rather than the camera resolution. Around 1920px wide is a common web starting point; smaller content images may use 1280px, with screen density also considered. Fewer pixels can save bytes, but the JPG output is not guaranteed to be smaller than the original HEIC.
Does resizing HEIC photos lose quality?
Downscaling removes pixels and source detail, and converting to JPG adds lossy compression. The result may still look good at its intended display size, but no quality setting guarantees invisible loss. Keep the original and inspect the preview; upscaling cannot recover missing detail.
