File Conversion & Handling

Export PDF pages as JPEG or PNG images in your browser (Mozilla pdf.js + canvas). Pick render scale, optional page list, and JPEG quality. Multi-page exports download as a ZIP. Max ~35 MB file size and up to 1000 pages (browser memory is the practical limit — use page ranges for huge jobs) — nothing is uploaded.

Stack JPEG or PNG files into one PDF with pdf-lib: reorder the list, choose A4 or Letter, set margins, and fit each image to the page — all client-side, no server upload. Up to 12 images per run.

Upload a PDF (up to 50 MB) and convert to a downloadable .docx via Dynamic Duniya’s file API — best for text-heavy PDFs; multi-column layouts and images may not transfer cleanly. Progress while uploading; open the result in Word or Google Docs and review formatting.

Upload Word .docx or legacy .doc (up to 50 MB) and download a PDF via the server file API. Output fidelity depends on LibreOffice on the server — review complex layouts. Progress while uploading; suggested download name converted.pdf.

Merge: first-page previews in a horizontal strip — drag cards to set merge order. Split: optional “Load page previews” then drag thumbnails (four per row, scrollable) to reorder pages before splitting by ranges or every N pages; ranges use preview slot numbers when previews are loaded. Zip when multiple parts. Client-side pdf.js + pdf-lib — max ~35 MB per file, 150 pages, 12 PDFs for merge.

Stamp text (font size, opacity, rotation, corner/center placement) or a JPEG/PNG image across every page using pdf-lib locally. Encrypted PDFs are not supported. Download a watermarked copy — your file never leaves the browser.

Upload a PDF (up to 50 MB) and extract tables into an .xlsx via the server file API. Toggle “Each page becomes a separate sheet”; pass separate_sheets to the backend. Best for PDFs with clear tables — scanned pages should use the Document OCR tool first. Download extracted.xlsx and review cell layout.

Image tab: multi-file JPEG/PNG (up to 12) with original and compressed previews; one output → single download, many → ZIP or download-each. PDF tab: same batch pattern with first-page previews (lossy raster rebuild per PDF). No uploads; ~35 MB per file cap.

Create a ZIP from many local files (append picks, DEFLATE or STORE) or open a .zip and download entries / selected subset as a new ZIP. JSZip in the browser — ~35 MB archive cap, no password support.

List paths, sizes, and dates inside a .zip without uploading. Optional text preview for small .txt/.json/.md files; download single files or use Create ZIP / Unzip for batch extract.

Batch-rename file extensions (replace last extension or append) with collision checks; download renamed files individually or as one ZIP — all in your browser, no upload.

Split any file into fixed-size or equal-count byte parts for transfer; parts download as a ZIP with an optional JSON manifest — client-side only, no upload.

Run OCR on scanned PDFs and images (JPEG, PNG, TIFF, BMP) up to 30 MB. Pick a Tesseract language, output plain text (.txt) or Word (.docx), and copy or download results after server-side processing.

Draw or upload a signature image (or type your name) and stamp it on every page of a PDF with pdf-lib — runs locally; this is a visual mark, not a cryptographic digital signature.

Paste plain text or HTML and generate a server-rendered PDF: choose font size (10–16 pt), A4 or Letter, and normal, narrow, or wide margins. Optional sandboxed HTML preview strips scripts for the iframe only. Download document.pdf via the file-tools API.

Convert .xlsx, .xls, or .csv (up to 30 MB) to a downloadable PDF via the server file API. Choose all sheets or active sheet only, portrait or landscape, and paper size (A4, Letter, A3). Download spreadsheet.pdf after processing.

Upload .csv (up to 10 MB) for server-side conversion to a PDF table. Preview the first rows in the browser; set portrait or landscape, A4 or Letter, optional row numbers, and bold first row vs plain header. Download spreadsheet.pdf.

Turn each PDF page into a slide image and build a downloadable .pptx in your browser (pdf.js + PptxGenJS). Slides are pictures — editable text is not preserved. Page and size caps apply.

Merge multiple PDFs in order, stack JPEG/PNGs into one PDF, or concatenate plain text/markdown files — all client-side. Office .docx merge is not supported here.
