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.Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size.

Frequently Asked Questions
How much smaller will my HEIC files be after compression?
Most HEIC photos shrink by 50 to 80 per cent. A typical 12MP iPhone photo of around 2 to 3 MB usually drops to 500 KB to 1 MB, depending on the level of detail in the image and the quality setting 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 10x15 cm, or social media. Extreme compression below 50 per cent quality may show softening or artefacts 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 the 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, as that changes both the 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 your 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 the Files app. Compression takes a few seconds per photo, then you can save the results straight back to Photos or Files.
What quality setting should I use when compressing HEIC photos?
Around 75 to 80 per cent quality is the sweet spot for most photos, cutting file size roughly in half with no visible loss. Choose 90 per cent or higher for photos you plan to print or edit later.

There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing.
