SW Toolbox

Compress, convert, resize & strip EXIF, decode HEIC, merge/split PDF, QR & more — 100% offline. Files never leave your device.

SW Toolbox processes images, PDFs, and QR codes on your device. Nothing is uploaded — there is no server, no account, and no analytics. • Compress JPG and WebP to a target size or quality. See before/after and percent saved. PNG downscales losslessly. • Convert between JPG, PNG, and WebP. • Smooth mosaic / pixelation blocks on photos you own (does not restore discarded pixels). • Strip EXIF, GPS, and other metadata from photos. • Decode iPhone HEIC to JPG or PNG. • Merge or split PDFs, or combine images into a PDF. • Generate a QR code from text or a URL and save it as PNG. • Right-click any image on a page to compress, convert, remove mosaic, resize, decode HEIC, strip EXIF, or save as PDF. • Right-click a PDF link (or a PDF page) to split it into one file per page. • Right-click selected text or a link to generate a QR code PNG. • Batch-process many images at once and download each result. • UI in English, 简体中文, 繁體中文, and 日本語 (Options → Language, or match the browser). Optional tips open Buy Me a Coffee in a normal browser tab. The extension only reads a file or selected text when you choose a right-click action.
