Terms for Local AVIF Conversion

Effective October 15, 2025

1. What the service actually does

  • The web page spins up dedicated Web Workers that stay inside your browser session.
  • Each worker tries to open AVIF files with native browser APIs (including createImageBitmap and OffscreenCanvas).
  • When the browser cannot decode the image, the worker loads the bundled @jsquash/avif WebAssembly module as a fallback.
  • No images are uploaded to a remote server; conversions occur entirely in volatile memory on your device.
  • Converted JPEG blobs are offered for download or packaging without leaving your browser.

2. Who may use the tool

  • You must be legally allowed to handle the files you submit, and you must grant yourself all permissions required to convert them.
  • The service is built for natural-person end users and teams testing it in a browser context; no automated scraping or bulk reselling.
  • You must be at least the age required to accept online terms in your place of residence.

3. Acceptable and unacceptable behaviour

You may:

  • Convert personal or professional images for legitimate workflows.
  • Run multiple conversions as long as you respect the browser resource limits.
  • Share feedback about bugs, including decode failures you encounter.

You may not:

  • Attempt to disable safeguards, reverse-engineer the workers, or tamper with the WASM package.
  • Upload content that is unlawful, harmful, or that you do not own.
  • Launch automated scripts that degrade the experience for other users.
  • Rebrand or redistribute the service without our written approval.

4. Technical boundaries and disclaimers

  • Output quality depends on source assets and the decoding path your browser chooses.
  • Low-memory or older devices may terminate workers, skip conversions, or produce slower results.
  • We cannot guarantee support for every AVIF feature set; some images will only decode through the fallback module, and a small subset may fail entirely.
  • The site is delivered “as is” without warranties of uninterrupted availability, non-infringement, or fitness for a particular purpose.
  • Our total liability for any claim related to this free tool will not exceed the amounts you paid us (currently $0).

5. Intellectual property

  • We retain all rights to the interface, code, worker orchestration logic, branding, and documentation.
  • You keep ownership of every file you convert. We do not store, catalogue, or claim rights over your inputs or downloads.

6. Changes to the service or these terms

  • We may modify the interface, worker strategy, or supported formats as we ship updates.
  • When we revise these terms, we will refresh the effective date and highlight material changes on the site.
  • Continuing to use the tool after an update means you accept the revised terms.

7. Getting in touch

Questions about these terms, decode failures, or permitted uses can be sent through the contact methods published on the site. We aim to respond within a reasonable timeframe.
