    Image

    Convert photos, screenshots and logos between JPG, PNG, WEBP, AVIF, GIF, ICO, TIFF, SVG and PDF.

    Document

    Convert Word, PDF, Markdown, HTML and plain-text documents into each other; turn PDF pages into images and pull out their text.

    Spreadsheet

    Convert Excel (XLSX, XLS), ODS, CSV and TSV spreadsheets into each other, into JSON and into PDF.

    Data

    Convert JSON, YAML, XML and TOML files into each other and into CSV or Excel tables.

    Audio

    Convert between MP3, WAV, M4A, AAC, OGG, OPUS and FLAC; turn WhatsApp voice notes (OPUS) into MP3 and rescue old WMA libraries.

    Video

    Convert MP4, MOV, WEBM, MKV, AVI, WMV and FLV videos, make GIFs from video, or pull the sound out as MP3.

    How it works

    Results in seconds

    Drop the file and choose the target; conversion starts at once and the result saves straight to your computer or phone. Drop several files together and get them all in one ZIP.

    No install, no account, no queue

    Open the page and drop the file. No queue, no email address, no watermark.

    A page for every conversion

    JPG to PDF, Word to PDF or MP4 to MP3: each conversion has its own page with the settings and the facts that matter for that job.

    Frequently asked questions

    Is donustur.io free?

    Yes. No account, no daily limit, no watermark and no paid tier.

    Can I convert several files at once?

    Yes. Drop files of the same type together and choose the target; they convert one after another and download as one ZIP.

    Which formats can I convert?

    280 conversions across 40 formats: images (JPG, PNG, WEBP, HEIC, AVIF, SVG…), documents (PDF, Word, Markdown, HTML), spreadsheets (Excel, CSV, ODS), data files (JSON, YAML, XML, TOML), audio (MP3, WAV, M4A, OPUS, FLAC…) and video (MP4, MOV, WEBM, MKV, AVI…).

    Why do some conversions take a moment the first time?

    To keep pages fast, heavy conversions such as PDF, HEIC and video take a few seconds to get ready the first time. After that they start right away.
