1Drop your HEIC images into the box above, or pick them from your device — there is nothing to install and no account to create.
2Choose how hard to squeeze: a quality or bitrate target, and optionally smaller dimensions if size matters more to you than detail.
3Start the job and let the workers re-pack the file; your original is never modified in place.
4Compare the new size against the original, then download the compressed HEIC file.
Compress HEIC FAQ
How does Compress HEIC actually make the file smaller?
+
Concretely, the HEVC image is re-encoded at a lower quality index; HEIC is already an efficient codec, so be realistic about the headroom — if you need a dramatic reduction, a well-tuned JPG or WebP will beat a recompressed HEIC. Nothing about it depends on you installing software: the job runs server-side and hands back a finished file.
How much smaller will my file get?
+
That is decided by the content, not by the tool. Photographic detail and film grain resist compression; flat colour, text and silence collapse. A realistic expectation is a large reduction on anything with big uniform regions and a modest one on a busy photograph or a high-motion clip.
Does the format of my file change how much I can save?
+
Very much so. this format is read and written by the same streaming pipeline as everything else we support. That determines both the headroom available and whether the saving costs you anything in fidelity.
Is there anything specific to HEIC I should know before compressing?
+
Yes — HEIC decoding needs the HEVC licence stack that Windows and most browsers ship without, which is usually the real reason the file is here at all. It is worth knowing before you overwrite an original you might need again.
What is the most common mistake when compressing HEIC images?
+
Compressing the same file repeatedly. Each pass on a lossy format is a fresh generation of loss and the savings shrink while the damage accumulates. Go from the original to your target in one step, and keep the original.
What do I get back, and can I control the trade-off?
+
A single compressed file per input, at a quality or bitrate level you choose rather than a fixed default. If the result is not small enough, changing the dimensions or the duration will do more than pushing the quality slider further down.
What can I upload to Compress HEIC?
+
HEIC and HEIF files straight off an iPhone or iPad, including 10-bit captures. You do not need the HEVC codec installed locally — the decoding happens on our side, which is usually the entire reason to do this in a browser.
Is there a file size limit on Compress HEIC?
+
Yes: free accounts process images up to 25 MB each, which comfortably covers iPhone HEIC captures — HEIC is roughly half the size of the equivalent JPG. A 12-megapixel HEIC is typically 1.5-3 MB, so the limit only becomes relevant for burst exports or 48 MP ProRAW-adjacent captures.
Will Compress HEIC lower the quality of my HEIC images?
+
HEIC stores a HEVC-coded image that is already very efficient, so the honest answer is that any re-encode costs a little. Where the operation can be applied without a full decode-encode cycle we do that; where it cannot, HEIC has enough headroom that the result is visually indistinguishable at normal viewing sizes.
Can I run Compress HEIC on several HEIC images at once?
+
Yes, and an iPhone export is usually exactly the case for it — drop the whole camera roll selection in and it processes in parallel with one set of settings.
Does the Live Photo / depth data survive?
+
No. The paired motion clip and the depth map are Apple container extras rather than part of the still image, and they do not survive processing. The still itself, its EXIF and its colour profile do.
Does Compress HEIC cost anything?
+
No. Compress HEIC is free, no account, no watermark, and no Apple device required at any point. Uploads are deleted shortly after the job finishes.
