HEIC Resizer

Resize iPhone HEIC photos for email, Instagram or upload forms - by percent, long edge or exact size, even under a set file size. Just need the format changed? Use HEIC to JPG.

How to Resize a HEIC Photo

  1. Add your HEIC photos. Drop one or more .heic or .heif photos from your iPhone or iPad into the box, or browse for them.
  2. Choose the new size. Use a percentage, a long edge such as 1920 px, an exact width and height, or a preset like Instagram 1080.
  3. Pick format and quality. Save as JPG, WebP or PNG, and optionally keep the file under 500 KB or 1 MB.
  4. Resize and download. Press Resize. One or two photos download directly, three or more come as a ZIP.

Why Resize iPhone Photos?

A modern iPhone photo is 12 to 48 megapixels - far more than most places need.

Email

Long edge 1280-1600 px keeps photos sharp on any screen and makes attachments 10x smaller.

Social

Instagram shows 1080 px wide; Facebook and X go up to 2048 px. Bigger uploads get recompressed anyway.

Forms

Visa, job and school portals often want a JPG under 500 KB or 1 MB - use the size limit.

Sizes vary with the photo - the tool always shows the real size before you download.

Tips

  • Keep the full size, only smaller files? Compress HEIC reduces the file without changing the dimensions.
  • Want a different format? See HEIC to PNG, HEIC to WebP or HEIC to PDF.
  • Just looking? Open a photo in the HEIC File Viewer.
  • Stop HEIC at the source: on iPhone, Settings, Camera, Formats, Most Compatible saves new photos as JPG.

Frequently Asked Questions

Drop your HEIC photos into the box, pick how to resize - half size, a long edge like 1920 px or an exact width and height - and press Resize photo. The preview shows the real result with its file size first.

Not in a browser - no browser can write HEIC files, so the result is a JPG, PNG or WebP (JPG works everywhere). If you really need HEIC again, convert the JPG with JPG to HEIC.

Pick JPG or WebP, open Format and quality and choose a size limit such as 500 KB or 1 MB. The tool tries quality levels until the real file fits - combine it with Long edge 2048 px for the best looking result.

JPG opens everywhere and is small - the best choice for photos. WebP is about 25-35% smaller for websites. PNG is lossless and keeps transparency, but is much bigger for photos.

Smooth is fast and looks great for most photos. Lanczos keeps fine detail a little crisper when you shrink a lot, but takes a moment longer. Pixel keeps hard edges for pixel art and screenshots.

Except in Safari, browsers cannot open HEIC by themselves, so a HEIC decoder runs inside the page. A 12-megapixel iPhone photo takes a few seconds; after that, resizing is instant.

Yes. Drop up to 50 photos; the same settings apply to all of them. One or two files download directly, three or more come as one ZIP.

No. Decoding, resizing and saving all happen in your browser, so your photos never leave your device. Want to remove the location too? Use the EXIF Data Remover on the JPG.
