Privacy-first QR, barcode, PDF, and image tools
Published by CaffeineByte
A privacy-first QR code scanner and barcode scanner with a QR code generator, scan history, and on-device PDF and image tools, now including a powerful PDF compressor. Process files locally — no account, no ads, no analytics.
New in 1.4
Compress PDF files directly on your device with High Quality, Balanced, or Maximum Compression. Compare original and compressed size, keep the source file untouched, and save or share the optimized copy.
Your file stays on the device. The result shows the original size, the compressed size, and the reduction percentage. Supports PDFs up to 100 MB — large files need more memory and can take longer.
Scan QR codes and barcodes with the camera, or scan codes from photos. Use batch scanning, keep a local scan history, and create QR codes to share or save.
Merge PDF files, split a PDF by pages or ranges, and turn images into a PDF. Files stay on your device unless you choose to save or share them.
Compress images and convert between JPEG, PNG, and WebP. Image tools run locally so you can resize and export without a cloud conversion service.
