Product idea

Smaller website images without sending files to a server

PixelPress keeps the image optimization 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.

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.

01

Offline image converter

Drop files or folders, press convert, and keep everything on your PC. PixelPress does not need a cloud upload or a return download.

02

WebP and AVIF for websites

Create modern image formats for faster pages, smaller assets, and better control before you publish a landing page, blog post, or product site.

03

Windows Pro optional, Linux free

Start free from the Microsoft Store on Windows. The Linux Debian release is always free, while Windows Pro unlocks larger batches and AVIF output for $11.59.

Flow

From heavy source folder to optimized web assets

  1. 1

    Add images

    Drop individual files or a full source folder into PixelPress.

  2. 2

    Choose output

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

  3. 3

    Convert locally

    Run the batch and get optimized files ready for your website build or CMS upload.

Why it is practical

The whole conversion stays close to your project files

PixelPress is designed for the repeated website asset task: test a quality setting, compare savings, and keep working without uploading private source images to a third-party optimizer.

Private by default Images stay on your machine, which is useful for client assets, unreleased product shots, and local drafts.
Built for repeated batches Windows starts free with an optional Pro unlock, and the Linux Debian release stays free from the public GitHub repository.
Website-focused formats WebP is included in Free and Pro, and AVIF unlocks in Pro when you need stronger compression.
No account flow Install from the Microsoft Store or download the Debian release from GitHub, then start converting without registration, tokens, or a browser upload step.
