convertfiles.online vs Smallpdf, iLovePDF, CloudConvert
We claim only what is true. The big players have more formats; we have shorter retention, no email gates, and batch ZIP on the free tier.

CloudConvert wins on format count. We focus on 13 formats done well instead of 200 done mediocrely.
Free file converter FAQ
Is it really free?
Yes. 5 conversions a day as a guest, 10 a day signed in. No card, no trial bait.
What happens to my files?
They live on our server only long enough to be converted and downloaded. After 1 hour, they're gone — and we never train models on your content.
What's the max file size?
50 MB per file. Up to 200 MB total per batch when signed in.
Why Google sign-in only?
Less friction than passwords, no spam, no SMS. We never see your contacts or anything else.
Do you put watermarks on free conversions?
No. Output is clean, no watermark. We do not believe in upgrade-pressure on the free tier.
Does it work on iPhone and Android?
Yes. The converter runs entirely in your mobile browser — Safari on iPhone, Chrome on Android. No app needed.
Can I convert multiple files at once?
Sign in with Google and use the batch uploader to convert many files at once. The result comes back as a single ZIP.
What formats are supported?
13 formats — PDF, Word (DOCX), Text, Markdown, HTML, RTF, ODT, EPUB, JPG, PNG, WebP, SVG, HEIC. 82 conversion pairs in total.
Will my converted file look exactly the same?
We preserve as much as the target format supports. Some properties (transparency in non-transparent formats, editable text in image formats) cannot survive the conversion.
Is there an API for developers?
Not yet — a developer-friendly API is on the roadmap. For now, the web converter handles batch via the signed-in uploader.
Your files vanish in 1 hour
Every file you upload is processed in an isolated job, over HTTPS, and deleted from our servers within one hour — both the original and the converted output. We do not train models on your content, we do not share files with third parties, and we do not require an account.
If you sign in with Google for a higher daily limit, you can also delete files manually from your account page the moment you finish downloading. We never store contact data, never sell email addresses, and never run ad-tracking pixels. Read the full privacy policy →
