Convert any supported file to AVIF

Turn just about anything into AVIF. Drop a file in and pick AVIF as the target, then compress, resize and rename in the same pass.

This hub accepts multiple input types when the conversion path exists. Output is always AVIF: The smallest of the lot. Next-gen compression that routinely halves WebP.

Enable compress after convert if the destination also publishes a KB maximum. Enable resize if it publishes pixel dimensions.

Typical sources people convert

Convert PNG, JPG, WebP, GIF, SVG, HEIC, PDF, DOCX, XLSX, PPTX to AVIF for free. Drop a file in and pick AVIF as the target.

If you already know the input format, dedicated pair pages load faster mentally (for example HEIC to JPG when every photo is from an iPhone).

Why portals ask for AVIF

Best for squeezing photos as small as they'll go for the web. Limitations: encoding is slower, and a few ancient browsers can't read it

AVIF is the lowest-friction format for reviewers who open files on older Windows PCs and web-only applicant tracking systems.

Recommended one-pass workflow

Upload the source file once.

Confirm AVIF output.

If the portal lists a KB max, enable Compress and set min/max kilobytes.

If the portal lists pixel size, enable Resize.

If the portal lists a filename, enable Rename before download.

Common upload failures (and fixes)

  • "Invalid format" — output type does not match spec (convert to the requested format)
  • "File too large" — enable compress to the stated KB cap
  • "Dimensions invalid" — enable resize to required width×height
  • "Wrong filename" — enable rename to match exact spelling

Why FilezyAI runs multiple steps together

Most free converters handle one job per visit: format change, or a vague quality slider, or a crop tool on another tab. Portals rarely ask for just one of those — they publish a checklist (JPG, under 200 KB, 600×600 px, named photo.jpg). FilezyAI applies every toggle you enable in a single server job.

Uploads are removed automatically two hours later. No account is required on the free tier. Pro removes ads and raises file-size limits.

  • Set min/max KB instead of guessing compression percentage
  • Chain convert, compress, resize, rename, and metadata removal before one download
  • Twelve input formats including HEIC, PDF, and Office documents
  • AI mode when you prefer plain-English instructions over manual toggles

How to use this tool

  1. Upload your source file (image, PDF, or Office doc).
  2. Select AVIF as convert target.
  3. Add compress, resize, or rename if the portal requires them.
  4. Apply changes once and download.
  5. Verify file type, size, and name locally before final submit.
