Universal File Converter

Universal File Converter converts files right inside your browser. Your files are never uploaded to any server. FEATURES • Images: convert between the common image formats, including WebP and SVG, and open iPhone HEIC photos. Adjust quality, resize, or compress to a target file size. GPS location data (Exif) is removed from converted images. • Documents and PDF: turn a Word document into a web page, a PDF or plain text; turn a PDF into images (one per page) or into text; make a PDF from Markdown or a web page; merge several PDFs into one; split a PDF by page or by page ranges. • Data: convert between the common data formats (JSON, CSV, XML, YAML), and generate a type definition or a database table from a JSON sample. • Offline OCR: extract text from images or scanned PDFs, in Vietnamese and English, running entirely in the browser. • Plain-background removal: turn a single-colour background into a transparent PNG. Works best for product photos and logos on a plain background; it is not meant for photos with complex backgrounds. • Text watermark: stamp a line of copyright text on the images you convert in batch (off by default). • Batch conversion, with all results downloaded as one ZIP file. • Right-click any image on a web page to convert it. The file keeps the image's name. • Paste (Ctrl+V) an image or data into the extension window to convert it right away. • Optional, off by default: when you download a .webp or .jfif image, a PNG or JPG copy is saved beside it. • Interface in English and Vietnamese. PRIVACY • Everything is processed on your device. The extension does not collect or send any file or data. • No account, no ads, no tracking. • The text recogniser and all libraries are bundled with the extension. No code is loaded from outside. • The extension has no access to any website when installed. The browser asks you for access only when you use a feature that needs it: for one site when you right-click an image served from another site, and for all sites when you turn on the optional auto-convert of downloads. The access is used only to fetch the image you asked to convert. NOTES • Password-protected PDFs cannot be opened. • OCR works best on sharp images; on blurry images or unusual fonts, accents may be misread.
