About Compression Levels
Each page is re-rendered at the target DPI and saved as a JPEG image inside the PDF. Text becomes non-selectable but the document remains fully readable. Choose Screen for the smallest file, Ebook for a balanced result, or Printer / Prepress for high-quality output.

Understanding PDF Compression Levels
What is a PDF Compression Level Chooser?
A pdf compression level chooser lets you select a named quality preset — Screen, Ebook, Printer, or Prepress — and compress your PDF to match that standard. Each preset targets a specific DPI (dots per inch) and JPEG qualitycombination, giving you predictable, repeatable results. Unlike a single-slider compressor, the pdf compression level chooser mirrors the industry-standard presets used by tools like Adobe Acrobat's "Save As Optimized PDF" dialog, making it easy to choose the right output for your workflow.
How Our PDF Compression Level Chooser Works
- Upload Your PDF: Drop your PDF into the upload zone or click to browse. The pdf compression level chooser loads a preview of all pages directly in your browser — no server upload required.
- Select a Compression Level: Choose Screen (72 DPI), Ebook (150 DPI), Printer (300 DPI), or Prepress (300 DPI max quality). Each preset shows its target DPI and expected file size impact so you can make an informed choice.
- Download Your Compressed PDF:Click "Compress PDF" and the tool re-renders every page at the chosen DPI, embeds the images as JPEG, and triggers an automatic download. The original and compressed sizes are displayed so you can see exactly how much space you saved.
What Each Compression Level Does
- Screen (72 DPI, ~55% JPEG quality): Produces the smallest possible file, optimised for on-screen viewing only. Ideal for email attachments, mobile sharing, and portal uploads with strict size limits.
- Ebook (150 DPI, ~72% JPEG quality): Balanced quality for digital reading on tablets and laptops. The recommended default for most sharing and web publishing use cases.
- Printer (300 DPI, ~85% JPEG quality): High-resolution output suitable for desktop and office printing. Preserves fine text and image detail at a moderate file size.
- Prepress (300 DPI, ~95% JPEG quality): Maximum quality for professional print workflows, commercial printers, and design agency submissions. Largest output file but highest fidelity.
Important Limitations to Know
The pdf compression level chooser re-renders each page as a JPEG image, which means text becomes non-selectable in the output PDF. The document remains fully readable and printable, but copy-paste and text search will not work. If you need to preserve selectable text, use the Compress PDF tool instead, which applies lossless object-stream compression without re-rendering pages. Additionally, PDFs that are already heavily compressed may show minimal size reduction at higher presets.

Frequently Asked Questions About PDF Compression Level Chooser
A pdf compression level chooser lets you select a named quality preset — Screen, Ebook, Printer, or Prepress — and compress your PDF to match that standard. Each preset targets a specific DPI and JPEG quality combination, giving you predictable results that mirror the industry-standard presets used by tools like Adobe Acrobat. The tool runs entirely in your browser with no server upload required.
Screen (72 DPI) produces the smallest file for on-screen viewing only. Ebook (150 DPI) is a balanced preset for digital reading and web sharing. Printer (300 DPI) maintains high resolution for desktop printing. Prepress (300 DPI, maximum JPEG quality) is for professional print workflows where the highest fidelity is required. Choose based on your intended output medium.
Yes. The pdf compression level chooser re-renders each page as a JPEG image and embeds it into a new PDF. This means text becomes non-selectable and non-searchable in the output. The document remains fully readable and printable. If you need to preserve selectable text, use the Compress PDF tool instead, which applies lossless compression without re-rendering pages.
Yes, completely. The pdf compression level chooser processes your file entirely in your browser using client-side JavaScript. Your PDF never uploads to any external server. All rendering and compression happens locally on your device. No data is transmitted, stored, or logged — your document stays 100% private.
Yes. The pdf compression level chooser is 100% free with no registration, no account, no premium tier, and no file size limits. You can compress unlimited PDFs at any quality level at zero cost. There are no ads or hidden charges.
Compression results vary by PDF content and the preset chosen. The Screen preset typically achieves 60–85% size reduction for image-heavy PDFs. Ebook achieves 40–70% reduction. Printer and Prepress achieve less reduction but preserve higher quality. PDFs that are already heavily compressed or contain mostly text may show less reduction at higher presets.
The pdf compression level chooser cannot process password-protected PDFs. You will need to remove the password protection first using a PDF unlock tool, then compress the unlocked file. This is a browser-side limitation — encrypted PDFs cannot be decoded without the password.
Both Printer and Prepress use 300 DPI, but Prepress uses a higher JPEG quality setting (95% vs 85%). Higher JPEG quality means less compression artefact removal, which results in a larger file. Prepress is designed for professional print workflows where maximum image fidelity is more important than file size.
The pdf compression level chooser processes one PDF at a time. To compress multiple PDFs, upload and compress each one individually — the process takes only seconds per file. For batch compression of multiple PDFs, use the Bulk PDF Compressor tool which processes multiple files simultaneously.
