HEIC Resizer
Resize
Enter one value and the other follows automatically while locked.
Saves your edited image at its current dimensions, keeping the original file format. The canvas shows exactly what downloads.
Your images are processed locally in your browser and never uploaded to any server.
Resizing HEIC photos normally means installing codecs or exporting through Apple Photos first. This tool skips all of that: the HEIC decoder loads in your browser on demand, you set the target dimensions, and the resized photo comes out as a standard JPG, PNG or WebP that opens everywhere. Aspect-ratio lock included, batches welcome, nothing uploaded.
How to use the heic resizer
- Add your .heic files (batch supported, up to 30 at once).
- Enter the new width or height, or a scale percentage. The aspect ratio stays locked.
- Choose the output format and quality. JPG is the compatibility default.
- Download each resized photo, or a ZIP of the whole batch.
Frequently asked questions
Can the output stay HEIC?
No, and any tool claiming browser-side HEIC output should be treated with suspicion: browsers cannot encode HEIC. The resized photo is saved as JPG, PNG or WebP. For sharing, uploading and editing, those formats are what you want anyway; that is usually the reason for resizing in the first place.
What size should iPhone photos be?
Modern iPhones capture at 4032×3024 or larger, which is far beyond what screens display. For the web, 1920px wide covers full-width use; 1280px suits typical content images. Resizing also shrinks file size dramatically, since pixel count drives bytes.
Does resizing HEIC photos lose quality?
The resampling is high quality, and the re-encode uses your chosen quality setting (85+ is visually lossless). Downscaling never loses visible detail: there was none at the larger size. Avoid upscaling beyond about 2×; no tool can invent detail.
