About

Most online converters upload your file to a server. Nibbo doesn't. Every tool runs on your own device. Video goes through your GPU with WebCodecs, and formats the browser can't decode go through FFmpeg compiled to WebAssembly. Your files never leave the browser.Video: compression (8/10/25/50 MB, Discord, WhatsApp, Telegram, email), trimming, merging, video to GIF, auto subtitles. Images: HEIC/AVIF/JXL/WebP/PNG/JPG conversion, compress to an exact KB size, resize, crop, upscale, background and object removal. PDF: merge, split, compress, sign, watermark, unlock/protect, PDF to Word/Excel/JPG/text, OCR in 25 languages. Audio: converter, cutter, loudness normalization, vocal remover, transcription. Plus ID-photo resizers, e-invoice viewers, QR, hashing, JSON and JWT tools.Free, no sign-up, no watermark, no queue, files up to 3 GB. Available in 16 languages.
