Compress almost anything.
Convert what makes sense.
Most jobs run on your device. Advanced LaTeX compilation uses our secure compiler only when you explicitly convert a TeX project to PDF.
Images, PDFs, data, documents, GIS, fonts and media are processed locally whenever the browser can do the job.
Legacy/proprietary formats without a reliable converter can still be compressed, but we do not invent meaningless output options.
TeX → PDF uses Tectonic, so equations, references and packages are compiled rather than rendered as plain text.
Supported families
The target list changes automatically for each file type.
PDF, DOCX/DOCM, ODT, RTF, TXT, Markdown, HTML, EPUB and presentation text extraction.
JPG, PNG, WebP, BMP, ICO, AVIF, HEIC/HEIF, TIFF, SVG and PSD → related images/PDF.
CSV, TSV, JSON, JSONL/NDJSON, XLS/XLSX/XLSB/XLSM/ODS, YAML, XML and TOML.
GeoJSON, KML, KMZ, GPX, TopoJSON, WKT and zipped Shapefiles → related GIS outputs.
MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, WMA, AIFF plus MP4, MOV, MKV, AVI, WebM, MPEG, MTS, FLV and more.
TTF, OTF, WOFF, WOFF2 and EOT conversions using a browser font engine.
ZIP ↔ TAR, TAR → TAR.GZ, TAR.GZ/TGZ → TAR/ZIP, plus generic lossless ZIP compression.
.tex projects can include .bib, .sty, .cls, images and secondary .tex files and compile to PDF.
Unknown/code/scientific/database files can still be losslessly packaged as ZIP rather than being offered nonsense conversions.
