Pick Smart format (recommended), a quality level, and optionally a target size such as “under 100 KB” or a resize like “max 1920px”.

Why “in the browser” matters
Most online tools upload your documents to a temporary server — they often sit in storage, may be visible to staff or subprocessors, and become a breach target. Compress Image skips the server entirely: your files are read from your device, processed in your browser's memory, and written back locally. Nothing to store, nothing to leak, nothing to delete later.
Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser using your device's own image codecs — nothing is transmitted. After the page loads you can even turn off your internet and keep compressing.
Will compressing an image reduce its quality?
That is exactly what you control. The Balanced setting (quality 75) is visually near-identical for typical photos, and every compressed image gets a before/after slider so you can inspect the result before downloading it.
Can I compress an image to an exact file size, e.g. under 100 KB?
Yes. Choose a target size (under 100 KB, 200 KB or 500 KB) and the tool automatically searches the right quality — and gently scales the image down if needed — until every output lands under your limit.
WebP or AVIF — which should I choose?
AVIF gives the smallest files (often 30–50% smaller than JPEG at the same quality), WebP offers the best balance of size and compatibility (supported by 95%+ of browsers). Smart mode picks the best format per image automatically.
Can I compress many images at once?
Yes — add unlimited images, set your options once and compress the whole batch with one click. Download them all as a single ZIP file when you are done.
Does it remove EXIF data and GPS location from photos?
Yes, automatically. Re-encoding an image in the browser produces a fresh file without camera metadata, so GPS coordinates and camera details never end up in the compressed image.
What happens to PNG transparency?
Transparent PNGs are never flattened onto a black background. Smart mode keeps transparency by converting them to WebP (which supports alpha), and “Keep same format” leaves PNGs lossless.
Can I compress HEIC photos from an iPhone?
Yes on Apple devices and any browser that can display HEIC — the image is decoded locally and compressed to JPG, WebP or AVIF. Elsewhere, convert to JPG first.
Is it really free with no limits?
Yes. No signup, no watermarks, no daily quota and no file-size cap — the browser does the work, so there is no server bill for us to pass on to you.
