What file formats should FCTtools support next?

Hi everyone,

I am preparing FCTtools, a free browser-based file converter for images, videos, and PDFs.

The goal is to make everyday conversion tasks quick without asking users to install desktop software. It currently focuses on common workflows around JPG, PNG, WebP, HEIC, PDF, MP4, MOV, and WebM.

I would love feedback from the Product Hunt community:

- Which file formats do you need most often?

- Do you prefer one focused converter per task, or one combined toolbox?

- What privacy expectations do you have for browser-based file conversion?

- Which workflow should be improved first: image conversion, PDF conversion, or video conversion?
