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.

Compress images
Adjust image quality or dimensions. Lossy output can change fine detail; preview text and edges before using it.
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.
