Watch Folder works properly again. Since version 1.5.2, adding a file to a watched folder, or switching Watch Folder off, made TrimrPix quit unexpectedly. Sorry about that. It is fixed, along with two quieter problems: a file still being copied into the folder could be skipped, and some files were optimized twice. You can also reach me straight from the app now. Help > Send Feedback… opens an email with your TrimrPix and macOS versions already filled in, and you see all of it before anything is sent.

WebP files are now skipped with a clear message instead of coming back unchanged. macOS provides no way to write WebP, so TrimrPix never could make those files smaller. Until now it handed the file back untouched, which looked like a file that simply had nothing to save. It now says so plainly, and leaves your file exactly as it was.

TrimrPix now handles scanned PDFs. Drag one in and it gets compressed like any image, often to about a third of its size, or let a Watch Folder do it for you. PDFs with selectable text are left alone on purpose. Re-encoding those would strip the text out and usually make the file bigger, so the app tells you instead of quietly ruining the document.

A fresh coat of paint. Colours across the app have been updated so everything sits together properly in both light and dark mode, plus some quieter fixes under the hood.

Optimizing a lot of images at once now shows live progress, so you can see how far along a batch is. Large image lists also load faster and scroll smoothly, with previews prepared in the background.

This update is all about reliability and performance: • Smoother batch optimization — "Optimize All" now uses less memory on large drops, so big batches stay fast and light. • Fixed a rare issue where removing an image mid-optimization could affect the wrong file. • More reliable Watch Folder monitoring. • Stability and performance improvements throughout. Thanks for using TrimrPix!

Fixed HEIC compression failing on some images. Added MetricKit for better crash diagnostics via Apple's built-in pipeline.

Smarter, smaller files across the board: Progressive JPEG encoding for 5-15% smaller JPEGs Lossy PNG quantization — up to 80% smaller PNGs GIF re-encoding with metadata stripping EXIF/GPS metadata removed from all formats Optional image resizing before compression New settings for PNG optimization and max image dimensions Fixed button styling issue

Smarter compression and bugfixes. Images that are already well-optimized are no longer replaced with a larger file. TrimrPix now keeps the original when compression would increase file size.

Version 1.3 brings real compression for modern image formats: • WebP compression — true lossy compression, not just validation • AVIF compression — next-gen format with excellent size reduction • HEIC support — compress iPhone/iPad photos natively on Mac • Improved PNG optimization — automatic alpha channel stripping for opaque images • Quality slider now applies to all formats (JPEG, WebP, AVIF, HEIC)
