Fit to send. Fit to submit. FitPDF.

Document processing

1. Choose a PDF. Select the document you want to reduce.
2. Review. FitPDF identifies the portions of the document that can be reduced safely.
3. Pick a size limit. 2 MB, 5 MB, 10 MB, 20 MB or any size you type.
4. Compress and download. FitPDF verifies the completed document before making it available for download.

Preservation controls

FitPDF is designed to preserve the functional and visual elements of a document while reducing its size. Before a completed document is offered for download, FitPDF checks that it remains suitable for ordinary use. If it cannot complete those checks, it will not offer the document as a completed result.

• Selectable, searchable text and OCR layers
• Vector graphics, fonts and page structure
• Links, annotations, form fields and bookmarks

Assembly and page order

Combine several PDFs and JPG/JPEG, PNG or WebP photos into one document, or simply rearrange the pages of one. Every page appears as its own card: type a new page number on it, drag it, remove it, or insert a blank page. Rearranging a single PDF rewrites that document in place, so its bookmarks, form fields, links and annotations are kept; combining several copies their pages into a new document, which the application says before you build it. Photos are fitted to the maximum output size you choose, and the whole assembly remains on your device.

Signing and annotation

Place your signature and type text anywhere on a PDF. A photograph of a signature is cleaned up on this device: the lighting across the paper is measured and flattened, the paper itself is removed, and only the ink is kept, so the signature sits on the page rather than covering it with a grey rectangle. Text and signatures are written into the page itself, so every reader shows them. This produces a visible signature; it is not a cryptographic digital signature, and FitPDF will not alter a PDF that already carries one.

Add text, images and redact PDF content

Add new text or images to any page, change their size and position, and undo or redo edits before downloading. To remove sensitive information, highlight supported page text and choose Redact selected text, or select an existing image and choose Redact image. FitPDF rewrites the selected PDF content instead of placing a cosmetic cover over information that remains underneath.

Batch PDF compression

Batch processing applies only to PDF compression; merging, organizing, adding content, signing and redaction use one workspace at a time. Batch PDF compression is currently included in the Free plan while paid checkout is unavailable. Queue multiple PDFs, process them locally and download the completed results as one ZIP archive.

Size-target verification

FitPDF works toward the size you select, whether you are meeting an upload requirement or an email attachment limit. It reports success only when the completed document is within that limit. Where the requested size cannot be reached without an unacceptable reduction in quality, FitPDF reports the best available result instead.
