Product concept

Smaller website images without uploading files to a server

PixelPress keeps the image optimisation loop on your own machine: use the Windows app or the free Linux Debian release, choose your output format, convert the batch, and publish lighter assets on your website.

Device-side conversion WebP and AVIF exports Free Linux edition No account

Highlights

Designed for rapid batch image optimisation before publishing

Use PixelPress when image size, page speed, and a private local workflow are more important than another browser upload tool.

01

Local image converter

Drop files or folders, hit convert, and keep all files on your PC. PixelPress requires no cloud upload or download.

02

WebP and AVIF for web pages

Generate modern image formats for quicker pages, smaller files, and greater control before publishing a landing page, blog post, or product site.

03

Optional Windows Pro, free Linux release

Begin with the free Microsoft Store app on Windows. The Debian release for Linux remains free, and Windows Pro adds larger batches plus AVIF output for £8.66.

Workflow

From large source folders to optimised web assets

  1. 1

    Add image files

    Drop single files or entire source folders into PixelPress.

  2. 2

    Select output

    Select WebP or AVIF, adjust quality, and keep the output folder visible.

  3. 3

    Process locally

    Run the batch and obtain optimised files ready for your website build or CMS upload.

Why it helps

The entire conversion remains close to your project files

PixelPress is built for repeated website asset tasks: test quality settings, compare savings, and continue working without uploading private images to third-party optimisers.

Privacy first Images remain on your own device, which is handy for client assets, unreleased product shots and local drafts.
Made for repeated batch processing The Windows app begins free with an optional Pro unlock, and the Linux Debian release remains free through GitHub.
Website-optimised formats WebP is included in Free and Pro; AVIF unlocks in Pro for stronger compression.
No account process Install via the Microsoft Store or open the Debian release on GitHub, then convert without registration, tokens or browser uploads.
