Shrink the file.
Not the photo.
Mass Image Compressor rips up to 90% off your image sizes and keeps every detail razor-sharp. Drop in a folder, walk away, and come back to a directory that loads instantly.
Drop it. Tune it. Done.
No queues, no cloud round-trips. The whole pipeline runs locally, so a thousand files finish while your coffee's still hot.
Drop a folder
Drag files or a whole directory onto the window. MIC walks every subfolder and lines up each image — including the RAW ones.
Tune the recipe
Pick an output format, dial quality against the live preview, resize, watermark, and choose which metadata gets to leave.
Export everything
Hit go. Progressive JPEGs, WebP, AVIF and retina sets land in your output folder, named exactly how you asked.
Everything, in one pass.
Photographers, web teams and game studios all reach for the same tool — because it does the boring stuff perfectly and gets out of the way.
Whole folders, recursively
Point it at a directory and it compresses every image inside — subfolders and all — mirroring your structure on the way out.
Conversions that hold up
Class-leading JPEG→WebP, PNG→WebP and HEIC→JPG. AVIF on the way out when you want the smallest possible byte count.
Speaks fluent RAW
Feed it straight from the camera — Canon, Nikon, Sony, Olympus and most other raw formats go in without a converter in sight.
Animation, end to end
Animated PNG, WebP and GIF go in and come out with every frame intact — just lighter. Perfect for sprite sheets and loops.
Metadata on your terms
Keep EXIF, IPTC and XMP intact — or strip GPS coordinates and serial numbers before a single file leaves your desk.
Retina exports, done right
Accurate @1x / @2x / @3x sets from a single source, plus resize-to-print-size when you need real dimensions.
If it's an image, it goes in.
▸ Accepts
Almost every popular format, plus the raw files from most Canon, Nikon, Sony and Olympus bodies.
◂ Delivers
Modern, web-ready formats — progressive, animated or retina, whichever the job calls for.
Give your images
a crash diet.
Thousands of files, ninety percent lighter, not a pixel out of place.
