Reduce the size and weight of your PDFs containing images and scans.
Our tool rasterizes (converts into compressed images) each page of your document before rebuilding a fresh PDF file. This is highly effective at slashing the size of PDFs containing scans, scanned invoices, or heavy graphics. Additionally, it flattens the text layer, preventing any copy-pasting actions (ideal for protecting corporate quotes or financial estimates). The entire execution is processed 100% locally on your machine.
Select the oversized PDF file you want to optimize directly from your device storage.
Choose your compression level (Low, Medium, High) to recalculate the structure of the pages.
Instantly download your optimized PDF document without any external network transfer.
PDF documents containing high-resolution scans, photos, or heavy graphics frequently exceed the critical file size thresholds allowed by email services (often capped at 20 or 25 MB) or public administration portals. Using an efficient tool to shrink PDF size is indispensable to slim down your files while maintaining complete clarity. Our online tool answers this logistical demand instantly, securely, and completely free of charge.
From an engineering perspective, this web application embeds the powerful pdf.js engine to decode and rasterize each page of the input document on a hidden HTML5 canvas element locally. The layers are then compressed into JPEG format according to your chosen compression ratio (Low, Medium, or High) before being reassembled into a brand-new vector structure via jsPDF. This process offers the massive advantage of flattening text layers, which freezes your data layout and acts as a barrier against fraudulent copy-pasting on commercial quotes or technical reports. Since your sensitive data remains contained in your browser session, security is total.
The \"Medium\" compression option provides an excellent technical compromise: background images and bulky scans see their file weights drastically split, while text characters retain impeccable crispness for the human eye.
Our script uses a local rasterization approach to optimize the spatial footprint of the document pages. Text components are fused directly into a high-fidelity, compressed graphical layer, protecting it against copy-paste exploits while thinning down the overall document weight.
