Create ZIP / Unzip Online

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.

Category: File Conversion & Handling

All ZIP work runs in your browser — nothing is uploaded. Uploaded archives are limited to about 35 MB and 150 files when creating a ZIP. Password-protected ZIPs are not supported.

Drop files here or click to add to the archive

Up to 150 files; each ≤ 35 MB. New picks append to the list.

Compression

Create ZIP in the browser

Add files from your device; new picks append to the list (up to the tool’s file cap). Duplicate names inside the archive are renamed automatically. Choose DEFLATE for smaller files or STORE for faster packing with no compression. Set the download name, then download your .zip — all processing stays on your machine.

Unzip and download safely

Open a .zip to see every path with compressed and uncompressed sizes. Entries that use unsafe paths (zip-slip) are blocked from extraction. Download one file at a time, or tick several extractable files and download them together inside a new ZIP. Password-protected archives are not supported.

Frequently Asked Questions

Are my files uploaded to your servers?

No. This tool uses JSZip inside your tab. Files never leave your device unless you save them elsewhere yourself.

Why is an entry marked blocked?

Paths containing sequences like parent-directory segments or absolute drive letters are rejected so malicious archives cannot trick the browser into writing outside a safe logical tree.

Tips

Quick guidance for using our tools safely and effectively.

Privacy

Files are processed on the server for conversion only and are not used for training or shared with third parties.

Best results

Use the formats suggested in each tool. Large media files may take longer — keep the tab open until processing finishes.

PDF to JPG / PNG

New

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.

PDF to DOCX

New

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.

DOCX to PDF

New

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 / Split PDF

New

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.

PDF Watermarking

New

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.
