JPEG compression
Choose a visual quality level and compare the original size with the finished output. Lower JPEG quality generally produces a smaller file.
Image compressor for macOS
Less file.
More privacy.
Compress images, resize batches, and remove embedded location and camera metadata. Every file stays on your Mac.

Focused by design
Everything needed for a clean image export.
CleanSlate combines compression, resizing, format conversion, and metadata removal in one native Mac workflow. There are no upload queues, accounts, or hidden cloud steps.
Metadata removal
Rebuild the output without copying source EXIF, GPS, XMP, IPTC, camera details, maker notes, comments, or embedded thumbnails.
Batch processing
Add one image or a complete group. The selected quality, format, dimensions, and destination are applied consistently to every file.
Image resizing
Limit the longest edge to 1,200, 1,600, 2,400, or 3,840 pixels while keeping the image proportions intact.
02
How it works
Three steps from source to share-ready.
- 1
Add images
Choose JPEG, PNG, HEIC, or TIFF files, or drag them into the app.
- 2
Choose the output
Set JPEG quality, format, optional dimensions, and where the new files should be saved.
- 3
Compress and clean
CleanSlate creates new files, reports the size difference, and lists the metadata removed.
Local by design
Your images stay on your Mac.
No uploads
Image processing happens on the device. Files are never sent to a CleanSlate server.
No account
There is no registration, login, cloud library, or synchronization service.
No tracking
The app contains no analytics, advertising, or third-party data collection SDKs.
Clear results
Review the output size, percentage saved, metadata bytes removed, and detected source fields.
03
Supported formats
InputJPEG, PNG, HEIC, TIFF
OutputJPEG, PNG, original format
PNG is lossless, so PNG output is not guaranteed to be smaller. Choose JPEG when substantial file-size reduction is the priority.
04
Common questions
Useful details before you start.
Does CleanSlate upload my images?
No. Image decoding, compression, resizing, and metadata removal happen locally on your Mac.
Which metadata is removed?
CleanSlate does not copy source EXIF, GPS, XMP, IPTC, camera details, maker notes, comments, or embedded thumbnails into the new image.
Can I process multiple images?
Yes. Add one file or many files and process the entire list with the same export settings.
Where are compressed images saved?
Save each result beside its original with _compressed added to the name, or choose a separate output folder.
Why did a PNG become larger?
PNG uses lossless compression, and an already optimized PNG may grow when re-encoded. For smaller files, choose JPEG and select an appropriate quality level.
CleanSlate for Mac
Smaller images.
Private by default.
