FileConv vs Erase.bg vs remove.bg: who gives free 4K downloads?
You've probably tried a "free" background remover and been handed a small, watermarked file — with the full-resolution version behind a credit purchase. If you want to remove a background in 4K and actually keep the 4K, the thing that matters most is the free export, not the AI demo. That's where FileConv, Erase.bg, and remove.bg differ most.

Free downloads and watermarks
FileConv. The download is the file you keep: no watermark, no account, no email gate. You can process as many images as you need, and the result is the same full-resolution PNG every time.
remove.bg. The well-known model: the free download is watermarked and limited in size, while high-resolution and upscaled exports are sold as paid credits. That's a fine product for some jobs — but if you're testing whether a free tool can give you a clean 4K cutout, remove.bg's free tier is not where you'll get it.
Erase.bg. An AI background remover that leans on a credit system for high-resolution and upscaled output. Useful for its use case, but the resolution you can download for free is tied to the credits you have.
4K / full-resolution output — the real test
The headline feature of a 4K background remover is that a 4K photo comes back as a 4K transparent PNG.
- FileConv removes the background at your image's full resolution — up to 4K (3840×2160) — and exports it there, for free. It does not down-scale to a 1080p ceiling and then charge to "upgrade" the resolution.
- remove.bg and Erase.bg can reach high resolution, but the full-resolution / upscaled output is the paid tier, not the free download.
If your goal is a clean, un-watermarked, full-resolution cutout without buying credits, FileConv gives that on the free tier.

- Free, no signup, no watermark, full-resolution up to 4K: FileConv.
