A DayFiles image tool

Last reviewed: August 23, 2026

Format Converter

Convert browser-supported image formats including JPG, PNG, WEBP, HEIC, and AVIF.

Format Converter is a task-first image tool inside the DayFiles ecosystem. Use this workflow when compatibility is the main problem and you already know the source format, destination format, or output style you need. It is designed for a fast browser workflow with immediate preview and download steps.

Part of the DayFiles product family alongside PDF DayFiles and Everyday Image Studio, with a stronger focus on image-specific workflows and local-first processing where practical.

Best for

  • Format-specific jobs where compatibility is more important than experimentation.
  • Users who already know the exact output they need for a form, CMS, or app.
  • Handing assets off into software that expects more familiar image formats.

What to expect

  • Format conversion solves compatibility problems, but it does not recreate detail that was already lost in the source.
  • Review the output-format tradeoffs before running the tool, especially transparency and file-size changes.
  • The best next step is often compression, resizing, or another export-oriented workflow.

Frequently Asked Questions

Which formats can Format Converter handle?

Format Converter supports common browser-friendly inputs and outputs such as JPG, PNG, WEBP, AVIF, and browser-decoded HEIC files.

Can I convert HEIC files without a server upload?

Yes. HEIC decoding happens in the browser, then the file is re-exported to your selected target format.

Can I choose output quality?

Yes. Quality settings apply to lossy outputs like JPG, WEBP, and similar exports.

Does it preserve transparency?

PNG and WEBP can preserve transparency, while JPG cannot.
