Bulk File Converter
Batch-convert many files at once in your browser — images between JPG/PNG/WEBP (with resize & quality), images to PDF, PDF to images or text, and text to PDF. No uploads, no CDN, and a single ZIP download. Only valid conversions are offered, so it never errors.
Bulk Converter — Convert Multiple Files at Once
Got a folder of photos to reformat and shrink for emailing? A stack of scans to turn into PDFs? A multi-page PDF to split into images, or a report to pull out as plain text? Doing them one at a time is painful. Our Bulk Converter handles a whole batch in one operation — drop the files, pick the target format, and download everything as a single ZIP.
It converts images between JPG, PNG and WEBP (with resize and quality control), images to PDF, PDF to images or text, and text to PDF — and it only ever offers you a target format your files can actually become, so it never throws a "can't convert" error. Everything runs in your browser: nothing is uploaded, and it doesn't even load a script from another server. No signup, no watermark, no cost.
How to Bulk Convert
1. Drop Files
Drag a folder or select multiple files at once — up to hundreds in a single batch.
2. Select Output Format
The dropdown shows only the formats your files can become. Set image quality, resize, and PDF page size where relevant.
3. Convert
Each file is converted with a live progress bar. Files that don't fit the chosen format are cleanly skipped, never errored.
4. Download ZIP
All converted files are bundled into a single ZIP archive for one-click download.
Bulk Converter Features
Image Batch Conversion
Reformat many images at once between JPG, PNG and WEBP, with a quality slider and optional resizing (max longest side, max width or scale %).
Images ⇄ PDF, PDF ⇄ Images
Turn a batch of images into PDFs (choose page size and orientation), or split PDFs back into per-page JPG/PNG images — and pull the text out of PDFs.
Only Valid Conversions
The output list is built from what your files can actually become, so you never pick an impossible target and get an error. In a mixed batch, files that don't fit are simply skipped.
Real ZIP, Built In-Browser
All outputs are packed into one standard, CRC-verified ZIP by our own code — no third-party ZIP or file-saver library, so nothing is loaded from another server.
One Setting, Whole Batch
Apply the same format, quality, resize and page settings to every file in the batch in one go, and watch a live per-file status as it runs.
Free and Private
Everything runs on your device — no uploads, no CDN, no signup, no watermark.
