File tools that never upload your files.
Convert, compress and resize images. Merge, split and rotate PDFs. Every one of these runs inside your browser tab — your documents stay on your device, because there is nowhere for them to go.
Tools
Free, unlimited, no account.
Convert images
Swap between PNG, JPG and WEBP in bulk. Choose a background colour when converting transparent images to JPG.
Compress images
Cut image weight with a quality slider and an optional size cap. Each result shows the percentage saved.
Resize images
Resize by width, height, exact dimensions or percentage — in bulk, with the aspect ratio kept.
Images to PDF
Combine images into one PDF with A4, Letter or fit-to-image pages and drag-to-reorder.
Merge PDF files
Combine any number of PDFs into one, in the order you choose. Nothing is uploaded.
Split, delete and rotate PDF pages
Extract, delete, rotate or split pages. Click page numbers or type a range like 1-3, 7.
PDF to JPG or PNG
Render PDF pages as images at up to 300 dpi. Pick pages, pick resolution.
Crop images
Crop to a social ratio or exact pixels, in bulk, with a choice of which edge to keep.
Rotate and flip images
Turn images by 90, 180 or 270 degrees and mirror them, a whole folder at a time.
HEIC to JPG
Convert iPhone HEIC photos to JPG or PNG in bulk, without uploading them anywhere.
SVG to PNG
Rasterise SVG artwork to PNG at any width, with transparency preserved.
Favicon generator
One image in, a complete favicon set out — ICO plus every PNG size a site needs.
Add page numbers to a PDF
Number the pages of a PDF, with control over position, format and starting number.
Watermark a PDF
Stamp DRAFT or CONFIDENTIAL across a PDF, with control over angle, opacity and colour.

Popular conversions
Straight to the one you need.
How it works
Three things make this different from the usual converter.
The browser does the work
Images go through the Canvas API and PDFs through pdf-lib, both running as JavaScript in your tab. There is no back end. Load the page, pull out your network cable, and the tools still work.
Nothing to leak
Hosted converters keep a copy of your file for hours or days. Since nothing is transmitted here, there is no copy to retain, no breach to be caught in, and no policy to trust. Check it yourself in your browser's network tab.
No arbitrary caps
Upload limits exist because bandwidth and storage cost money. Neither applies here, so there is no 10 MB ceiling, no daily quota, no queue, and no upsell to a paid tier at file number three.
Good to know
Your files are never sent anywhere. The one thing your browser does fetch from the network is the code for the tools themselves: the PDF library from a public CDN, and the fonts. Those requests carry no information about your files.
Re-encoding strips metadata. When an image is converted, compressed or resized, EXIF data — including GPS location, camera model and capture time — is discarded. That is usually what you want before publishing a photo, but keep your originals if you need it.
Some things genuinely need a server. OCR on scanned documents, PDF-to-Word conversion with layout reconstruction, and removing passwords from encrypted PDFs are not offered here, because doing them well in a browser is not yet realistic. Better to say so than to do them badly.
