PixCrunch — Offline Image Compressor & Resizer

Stop uploading your photos to random compression websites.

PixCrunch batch-compresses, resizes and converts images entirely inside your browser — typically 50–90% smaller files. No install. No account. No upload. No internet after download.

What it does

• Batch compress — drop individual files or a whole folder, process them in one click
• Resize — max width, fit within a square bound, or scale by percentage
• Convert — PNG, JPEG and WebP output (GIF & BMP input supported)
• Before / After preview — compare original vs result side by side
• ZIP export — download all results in one click
• English & Japanese UI

Free vs Full

Free: up to 10 files per batch.
Full: unlimited files per batch plus target size — set a limit like 500 KB and every file is automatically tuned to fit under it.

100% offline by design

PixCrunch contains zero network code. Images are re-encoded inside your tab — metadata like EXIF (including GPS location) is always stripped, and nothing is ever uploaded. It keeps working forever, even offline, from a single HTML file. Double-click, done.

Requirements

Any modern browser (Chrome, Edge, Firefox, Safari). Works on Windows, macOS, Linux.

You own your images

Processed images are 100% yours — use them in commercial projects, free of royalties. The software itself is licensed (no redistribution of the tool). See LICENSE.txt inside the ZIP.
