Technical note

THF to WEBP: what to expect from the conversion

A THF file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same THF looks different in every program that opens it. The WEBP render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. THF coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. WEBP is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the THF original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as WEBP opens on any computer and any phone. reaConverter produces those from THF in batch, entirely offline.

  • Render every file in a folder to WEBP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

I use reaConverter's Watch Folder feature to automatically convert any WebP image dropped into a specific folder to JPG. This automates my entire image processing pipeline. Set it and forget it – that's how professional tools should work.

Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster.

I had a huge archive of WebP images from a client that I needed to convert to TIFF for printing. reaConverter handled it flawlessly – 500+ files in one go. No crashes, no quality loss. I'm genuinely impressed by the stability.

I download memes and graphics all the time, but half are WEBP files that won’t open in my editing apps. reaConverter fixes this in two clicks. Now I can actually use the funny cat pics I save!

FAQ

THF to WEBP Conversion

What are THF files?

THF is the main file of a package in EDIGEO, the French standard for exchanging digital geographic data, and it is best known from the French cadastral plan, the digital map of land parcels that the tax administration makes available for every commune. A single EDIGEO delivery is made of several files with the same base name, and the THF file is the one that stands at the top: it describes the transfer as a whole and tells which other files belong to it. By itself it holds no map, and the parcels, buildings, and boundaries are in the other files of the package. Such packages are published openly for the whole of France and are widely used to produce local maps and to import cadastral data into other systems.

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
