Compress iPhone Photo for Sharing (Under 3 MB)
iPhone camera photos are typically 4–8 MB HEIC. Compress before sharing.
Your images stay on your device. Nothing is uploaded.
iPhone 15 Pro photos average 4–8 MB in HEIC format and much larger as full-quality JPEG exports. For AirDrop or Messages sharing at scale, compressing to under 3 MB per image dramatically speeds transfer.
This preset produces a 2400 px JPEG at quality 90 — visually indistinguishable from the source, one-quarter the file size.

- The default format for iPhone Photos share is JPEG at the preset above — chosen for the format's rendering compatibility and byte efficiency in this context.
- Will compression break transparency or animation?
- Transparency is preserved when the output format supports it (PNG, WebP, AVIF). Animation is preserved for animated WebP. JPEG output flattens transparency to white.
- Can I compress dozens of images at once?
- Yes — use the bulk compressor. Drop a folder or multi-select files; the queue processes them in order with progress per file, and you can download all results as a ZIP.
- Do my images get uploaded anywhere?
- No. The tool runs entirely in your browser — important for client work, internal assets, and anything not yet published.
