WORKLAZY TOOLS

Add PDF Stamps & Signatures

Freely position and resize signature or stamp images, and apply them across multiple PDF pages at once.

Use this tool directly in your browser without installing software or signing in.

• PNG and JPEG images
• Direct move and resize
• Fixed aspect ratio
• Selected-page placement
• Same relative position
• Undo and redo

Page-level editing

Drag previews to reorder pages and remove unwanted pages. For PDFs by range, choose a range in the output workspace on the right and use page checkboxes, or quickly split the document between pages.

If a source page is already rotated, your rotation is added to its existing orientation so the exported page matches the preview.

Local processing and file lifetime

PDFs, images, and download links live in browser memory. Refreshing or closing the tab clears the current selection and any undownloaded result.

The site, advertising, and OCR model assets may use ordinary network requests, but your work files are not sent to a conversion server.

Protected PDFs and signatures

Password-protected PDFs are not supported. Use a legitimately unlocked copy provided by the document owner.

Merging, rotating, splitting, or rebuilding a PDF invalidates existing digital signatures. Forms, bookmarks, links, attachments, and advanced objects may not survive page copying.

Quality and performance

Reordering and extracting pages normally copies original PDF pages rather than rasterizing them. Image conversion and searchable OCR PDFs render pages at the selected resolution.

More pages and higher resolution increase processing time, memory use, and output size. Previews render lazily at lower resolution to keep long documents responsive.

What is the difference between editing text in a document and organizing pages?

Use page editing to merge submission files into one or keep only the necessary pages. This is not for rewriting text content, but for organizing the sequence, structure, and orientation of pages.

Choose PDF to Image to use pages like photos, or Image to PDF to bind multiple photos into one document. Use Document Conversion to bring PDF text into an editable document, or OCR to add searchable text to scanned documents. Always compare the result with the original text after conversion.

Examples and Selection Help

Common task examples: Try "Combine 3 submission documents into one" → Merge feature, "Save only pages 2-4 of a contract" → Split/Extract feature, "Convert entire pages to PNG" → Image conversion, "Search words in a scanned document" → OCR feature.

Does adding a stamp image make it a certified digital signature?

Place a prepared PNG or JPG stamp or signature image in the desired location. Check the image's margins, size, orientation, and the actual page where it will be applied. Since this is simply overlaying an image, do not use it as a cryptographic electronic signature to verify the signer's identity or document integrity.
