Highlights from v1.1.0 (view full release note)
I’m delighted to present some much-requested features in this release, including support for HEIC file conversion!
- Added support to convert
HEIC,AVIF→JPG,PNG,WebP. - Paste image/files from clipboard to start optimization.
- When setting a file size limit, you can switch between units MB and KB.
- Remember last-used settings, stored locally in the browser.
The support from the community has been incredibly encouraging, and with over 4500 docker pulls, the project is now humbly making its way toward a 500 stars milestone.
The project also received its first donation, which I’m incredibly grateful for!
I just tested the new release. Consider defaulting PNGs to convert to JPEGs unless they have a PNG-specific feature like transparency. Lots of screenshots are initially PNGs, but not because they need any PNG-specific features. Consider: In a test screenshot, it compressed 3.4% with the default 80% setting and PNG->PNG, but for PNG->JPG, it compressed 84.6%.
The conversion option “Default” is meant to retain the file format when possible, but you can actively select the other options like jpg or webp if that fits your use case better.
