PixelPress for WebP and AVIF images
PixelPress WebP and AVIF image converter for JPEG, PNG, WebP and AVIF images on Windows and Linux
Compress JPEG, PNG, WebP, and AVIF files into smaller WebP or AVIF website assets on your device. PixelPress keeps originals untouched, avoids uploads, and ships through the Microsoft Store for Windows plus a free Ubuntu and Debian release on GitHub.

Product idea
Smaller website images without sending files to a server
PixelPress keeps website image optimization local: add files or folders, choose WebP and AVIF output, keep source images untouched, and publish lighter assets without sending client or product images to a browser service.
Features
Built for fast batch image optimization before publishing
Use PixelPress when image size, page speed, and a private local workflow matter more than another browser upload tool.
Local batch image optimizer
Compress website folders on your own machine. PixelPress reads JPEG, PNG, WebP, and AVIF sources without sending private images to a cloud service.
WebP and AVIF for websites
Create modern output formats for faster pages, smaller assets, and better publishing control before a landing page, blog post, or product site ships.
Originals stay untouched
Optimized copies are written into an output folder while source images stay where they are, so your original files remain the source of truth.
Fresh or replaceable output folders
Create a fresh output folder for every run, or reuse a PixelPress-created output folder when repeated batches should stay tidy.
Resize large images for the web
Optionally scale images wider than 1920 pixels down for practical web output while preserving aspect ratio and leaving smaller images alone.
Windows Store plus free Linux release
Start free on Windows through the Microsoft Store, unlock Pro for larger Windows batches and AVIF output for $11.69, or use the free Ubuntu/Debian release from GitHub.
Flow
From heavy source folder to optimized web assets
- 1
Add images
On Windows, drag files or folders into PixelPress or use the pickers. On Linux, choose files or folders with the in-app picker buttons.
- 2
Choose output
Select WebP, AVIF, or both, set quality, choose a separate output folder, and decide whether each run gets a fresh folder.
- 3
Convert locally
Run the batch, watch progress, then open the output folder to review generated files, size savings, and conversion duration.
Why it is practical
The whole conversion stays close to your project files
PixelPress is designed for repeated website asset work: adjust quality, resize very wide images when useful, compare savings, and keep working without uploading private source images to a third-party optimizer.
Use cases
Made for the image tasks that slow websites down
Landing pages
Shrink hero images, feature screenshots, and visual assets before they hit production.
Blogs and docs
Turn large PNG and JPG folders into lighter article images without leaving your desktop.
Product screenshots
Prepare software screenshots for stores, changelogs, tutorials, and support pages.
Client work
Optimize delivered image folders locally when source files should not move through a third-party web tool.
Screenshots
The desktop workflow from input to final savings
Move through the PixelPress workflow and inspect the conversion screens before choosing the Windows app or Linux Debian release.
Local import
Add files or folders locally and prepare conversion without upload.
