Compress HEIC
Reduce HEIC/HEIF file size from iPhone photos. Maintain quality while saving storage space.

About HEIC Compression
HEIC (High Efficiency Image Container) is the default image format for iPhone and iPad photos. HEIC provides excellent compression while maintaining high quality, making it perfect for storing photos. Our HEIC compression tool further reduces file sizes, helping you save storage space on your devices while keeping your photos looking great. Whether you are optimizing assets for a US-hosted site on AWS, Cloudflare, or Vercel, trimming email attachments for Gmail and Outlook, or submitting documents to federal portals, this tool keeps your files lean and your workflow fast — all without uploading anything to a server.
Optimized for Users in the United States
If you are working in the United States, file size matters for email providers like Gmail (25 MB attachment cap), Outlook, and popular US hosting platforms. Compressing images and documents before uploading to Amazon S3, Cloudflare, or Netlify keeps your bandwidth costs down and improves Core Web Vitals for American visitors on both fiber and mobile networks.
- Most US email services reject attachments above 25 MB — compress to stay under that limit without switching to Google Drive or Dropbox.
- For US-based e-commerce on Shopify, aim for product images under 200 KB to keep your Google PageSpeed score competitive.
- Social platforms popular in the US — Instagram, Facebook, X (Twitter), and LinkedIn — each re-encode uploads, so feed them the smallest high-quality source file you can.
- Many US government and healthcare portals restrict document uploads to 5–10 MB; pre-compressing PDFs avoids upload failures.

Frequently Asked Questions
How much smaller will my HEIC files be after compression?
Most HEIC photos shrink by 50 to 80 percent. A typical 12MP iPhone photo around 2 to 3 MB usually drops to 500 KB to 1 MB, depending on image detail and the quality level you choose.
Does compressing a HEIC file reduce image quality?
Slightly, but usually invisibly. Our tool targets visually lossless results, so photos stay sharp for sharing, printing at 4x6, or social media. Extreme compression below 50 percent quality may show softening or artifacts in detailed areas like textures and text.
Can I compress multiple HEIC photos at once?
Yes. Batch compression lets you upload dozens of HEIC files at the same time, often up to 20 or more per batch. Every photo is processed with the same quality settings, and you can download all compressed files together in a ZIP archive.
What is the maximum HEIC file size I can upload?
Files up to 50 MB work fine, which covers virtually every iPhone photo, including 48MP shots from recent Pro models. Larger files may need to be resized or split before uploading.
Will compressing HEIC convert my photo to JPG?
No, the output stays in HEIC format, so you keep the smaller native file type and features like HDR. If you need JPG instead, use a dedicated HEIC to JPG converter, since that changes both format and compatibility.
Are my iPhone photos safe when I upload them to compress?
Yes. Uploads are transmitted over HTTPS encryption, processed automatically, and deleted from our servers within one hour. No one views your photos, and nothing is stored long term, so private pictures stay private.
How do I compress HEIC photos on my iPhone?
Open this page in Safari, tap the upload button, and choose photos from your library or Files app. Compression takes a few seconds per photo, then save the results directly back to Photos or Files.
What quality setting should I use when compressing HEIC photos?
Around 75 to 80 percent quality is the sweet spot for most photos, cutting file size roughly in half with no visible loss. Choose 90 percent or higher for photos you plan to print or edit later.
Will this work with my Gmail or Outlook attachments?
Yes. Gmail and Outlook both cap attachments near 25 MB. Our tools can shrink most files well under that limit so you can attach them directly instead of linking to Google Drive or OneDrive.
Can I use this for sensitive business or healthcare documents?
Since all processing happens locally in your browser and nothing is uploaded, your files never touch our servers. This client-side approach supports privacy-conscious US workflows — still follow your own organization's data policies.
Does it work on Mac, Windows, and mobile?
Yes. Our tools run in any modern browser on macOS, Windows, ChromeOS, Linux, iOS, and Android. No downloads or installations required.
Is there a file size limit?
Most tools handle files up to 50 MB each. For larger files, process them in smaller batches for the smoothest experience.
