About this tool PDF Heaven — Free PDF Tools
CalcPlanet's PDF Heaven free PDF tools handle the everyday document tasks that normally cost money or require shady uploads — compress bloated PDFs for email, merge a stack of receipts into one file, split a 200-page contract into chapters, or convert images and PDFs in either direction. Every action runs locally in your browser using the open-source pdf-lib and pdf.js engines, so your documents never touch a server.
Browser-based processing is particularly helpful for private records, contracts, applications and invoices, because you do not need to send those documents to a third-party conversion service. The tools are free without an account, watermark or monthly quota, but very large files are limited by device memory. Complex PDF-to-Office conversions may alter formatting, so always check the downloaded result.
Need to work with images first? Try our image tools — compress JPGs to under 1 MB before bundling them into a PDF.

Frequently asked questions
Are my PDFs uploaded to your servers?
No. Every PDF tool runs 100% in your browser using pdf-lib and pdf.js. Your documents never leave your device, even on mobile.
Is there a page or file size limit?
There is no paid quota, but practical limits depend on your browser, available memory and the document itself. Large scanned PDFs can fail on phones; try a desktop browser or smaller batches.
How much can the PDF Compressor reduce file size?
Results depend on how the original PDF was built. Preserve text mode keeps text and page contents but may not reduce size. Smaller images mode can shrink scans more, but converts pages into images.
Will the merged PDF preserve quality?
Yes — Merge PDF copies pages losslessly, so quality is identical to the source files. No re-compression is applied.
Can I use these tools on mobile?
The core workflows support modern mobile browsers. For merging, use the Move Up and Move Down controls to reorder PDFs by touch or keyboard. Very large files can exceed mobile memory.
