More than a converter

The two jobs people pay subscriptions for — wrangling PDFs and turning speech into text — run here for free, locally, with no page or minute caps.

Everything under one roof

Instead of hunting for a different single-purpose site per format, AllConverter routes each file to the right engine — canvas for images, a document pipeline for text, and a full FFmpeg build for media.

Images

PNG, JPG, WebP, AVIF, BMP, SVG, HEIC, GIF → any raster format, favicon sets or PDF.

Documents

Markdown, HTML, TXT, RTF and PDF — including text extraction from real PDFs.

Data

JSON, CSV, TSV, YAML, XML, NDJSON and SQL inserts with nested-field flattening.

Audio

MP3, WAV, OGG, M4A, FLAC, AAC and Opus with bitrate and trim control.

Video

MP4, WebM, MKV, MOV, AVI — plus GIF loops, audio extraction and frame grabs.

Special tools

PDF page rasterising, ICO favicon packs, table-to-document rendering, ZIP bundling.

Private by design

Every conversion runs inside your browser tab. No uploads, no queue, no retention.

No waiting rooms

Work starts the moment you drop a file — no accounts, no daily caps, no email walls.

Guided, not guessy

We only offer conversions that make sense, then ask the questions that change the result.

How a conversion actually works here

  1. 1

    Drop a file. AllConverter inspects the extension and MIME type to identify the real format.

  2. 2

    Pick a destination. Only genuinely valid targets are offered, grouped by what they are good for.

  3. 3

    Answer the questions that matter — quality, resizing, transparency backdrop, delimiter, bitrate, page range.

  4. 4

    Convert locally and download. Multi-page output is bundled into a ZIP automatically.
