A no-sign-up toolkit for shrinking images, shrinking PDFs, and merging PDFs — everything processed in memory through a Python backend, nothing stored after the response goes back.

The Problem

Shrinking a photo or a bloated PDF for email or upload usually means signing up for a web tool, and merging multiple PDFs into one is rarely free. PLS Compress needed no account and left nothing stored server-side.

Overview

PLS Compress rebuilds a PDF's internal structure with pikepdf and, where it's safe to do so, re-encodes oversized embedded photos at a lower quality — page text is never touched, so documents stay sharp and stay searchable. Images are re-encoded through Pillow with a chosen format, quality, and optional width cap, with EXIF rotation respected. Every tool shows a before-and-after size comparison and percentage reduction before download. The frontend is server-rendered HTML with a single Jinja2 template and vanilla JS — no build step, no framework, so anyone can clone the repo and run it immediately.

Features

• Image compression (JPG/PNG/WEBP/BMP) with format, quality, and width controls
• EXIF-aware rotation handling
• PDF compression that re-encodes oversized embedded images without touching page text
• Merge 2-20 PDFs into one, in upload order
• Before/after size comparison with percentage reduction
• In-memory processing — no database, no persistence, nothing stored after the response
