Private browser PDF tools

Work with PDFs, privately

Merge PDFs, extract pages, turn images into a PDF, or add text and drawings. Choose a task and work locally, without an upload.

Choose your local files.

Choose files to load the local PDF workspace. Nothing is uploaded or stored by Aftermath.

Choose PDFs to mergeSelect two or more PDFs · ordered and combined locally.The local PDF workspace loads after you choose a file.

Choose a local PDF task

Merge flat PDFs in a chosen order, split selected pages or ranges into a ZIP, put JPG, PNG, or WebP images into a PDF, or add new text boxes and freehand drawing overlays. JavaScript activates the private browser workspace on this page.

Four focused PDF tasks, without a crowded toolbox

Merge combines multiple PDFs into one document in the order you choose. Split reads one PDF and creates a ZIP with one new PDF for each selected page or comma-separated page range. Images to PDF makes one document from JPG, PNG, or WebP images in the order you set. Edit opens one PDF in a local review canvas so you can add text boxes and freehand drawing overlays. Every task keeps source files in the current browser session instead of sending them to an upload service.

Review order, pages, and additions before exporting

For a merge, drag PDF rows into the exact output order or use the keyboard move controls. For a split, enter individual page numbers or ranges such as 1-3, 5, 8-10. Each comma-separated entry becomes one output PDF, while a blank selection creates one PDF per page. For an edit, place a new text box or draw with the pencil, then review the flattened result before downloading.

Questions people ask

Are my PDFs uploaded to Aftermath?

No. Reading, merging, splitting, annotating, and ZIP creation happen in your browser. The app has no PDF upload endpoint, account storage, or server-side document job.

Can I use the PDF tools offline?

After the page and its local PDF code have loaded, the operations themselves do not need a network connection. You still need enough memory in your browser for the documents you select.

What PDF limits currently apply?

The workspace accepts up to 25 PDFs, up to 100 MB each and 300 MB across a selected batch. It checks up to 1,000 pages per input PDF, allows up to 2,000 pages in one merge, and accepts split sources up to 50 MB for up to 250 output PDFs per run. Browser memory can impose a lower practical limit.

Can I process filled, signed, or encrypted PDFs?

No. To avoid creating a document with broken fields or unverifiable signature data, Aftermath accepts only flat, readable PDFs. It rejects encrypted or permission-restricted files and files containing interactive form or signature data. Keep the original and use an authorized flattened copy or a dedicated PDF application.

Choose a tool

Use the PDF workspace to merge, split, edit, inspect, normalize, or create a PDF from images without uploading the source files. Each focused action states its accepted input and creates a separate report or document when supported. Review the new document before sharing it, especially if the source uses features this browser-local workflow does not rewrite.

Choose by the result you need

Need	Focused route	Why it matches
Combine several flat PDFs in a chosen order.	Merge PDFs in the order you choose	Merge preserves explicit queue order and reopens one separate output.
Extract page ranges into separate PDF files.	Split a PDF into the pages you need	Split parses visible page groups and packages the selected outputs.
Inspect mixed page boxes, size and rotation before editing.	Inspect every PDF page size before it causes a layout problem	The inspector reports geometry without rewriting the source.
Turn ordered JPG, PNG, or WebP images into one PDF.	Put JPG, PNG, or WebP images into one PDF	The image-to-PDF route owns page order, fit, margins, and paper geometry.
Add new text boxes or freehand marks to a flat PDF.	Add text and draw on a PDF locally	The annotation route creates overlays without claiming existing-text editing or redaction.
Create an A4 or Letter copy with an explicit fit consequence.	Normalize a PDF to A4 or Letter with an explicit fit choice	The normalizer owns padding, cropping, and canvas-only page changes.
Inspect and optionally clear common PDF document metadata.	Inspect and clear common PDF metadata before you share a copy	The metadata route distinguishes field cleanup from visible-content redaction.
Review probable blank pages before optional removal.	Find probably blank PDF pages, then decide before removing them	The detector requires human confirmation and never removes a page automatically.

Check before sharing

A local measurement or export does not guarantee acceptance by an external destination.
