FAQ

Questions we actually get asked

Honestly? I got tired of paying for tools that do one simple thing. Background removal, file conversion — these aren't complicated operations, but every service out there wraps them in paywalls, subscriptions, or watermarks. I wanted something that just works, for free, without the hassle. So I built it. I also wanted something I could actually use myself without thinking twice about it. If it helps other people along the way, that's a bonus.
Yep, totally. The free tier requires zero signup, zero email, zero anything. You just open the app, drag your image in, and hit go. We track usage by IP address to enforce the 10-per-2-hours limit — that's it. No cookies, no profiles, no creepiness. If you hit the limit and want more, that's what the paid plans are for.
Free users get a pool of 10 background removal operations and 10 conversion operations. These refresh every 2 hours from the first time you use the tool. So if you use 3 at 9:00 AM, your full 10 come back at 11:00 AM. It's per-tool — meaning removals and conversions have separate counters. If you sign up (even for free), your quota is tied to your account rather than your IP, so it follows you across devices.
When multiple people use the tool at the same time, jobs are processed in a queue. Ultimate users always go to the front of the line, then Starter users, then free users. During off-peak hours this doesn't matter much — you won't notice a difference. During busy periods, paid users will get their results faster while free users might wait a bit longer. Think of it like the fast lane at the airport.
Absolutely not. Your images are processed entirely in memory — they're never written to disk. The moment your result is sent back to you, the data is gone. We don't log image content, we don't store results server-side, and we certainly don't use your photos to train models. RnBulkTools is a tool, not a data vacuum.
API access is free for everyone — you don't need a paid plan. Sign up, verify your email, then go to Account → API tab to generate your key. Pass it as an X-API-Key header on POST /remove-bg and POST /convert. Your API calls share the same quota as your plan — 10 ops / 2h on Free, 100 on Starter, unlimited on Ultimate. The key difference on Ultimate is unlimited volume, no quota windows, and top processing priority.
Pretty good, honestly. We use ISNet (isnet-general-use), a modern deep learning model that handles most common cases well — products, portraits, objects with clean edges. It handles hair and fur reasonably. Where it struggles: extremely busy backgrounds, very low contrast between subject and background, or tiny detailed subjects on complex patterns. For studio-style photos or product shots it tends to nail it. For complex composites, you might want to touch up edges manually.
Yes. The output is yours, full stop. We don't put any watermarks on results and we don't claim any rights to images processed through RnBulkTools. Use your transparent PNGs for whatever you want — print, web, commercial work, client deliverables. The AI model (ISNet) is open source under Apache 2.0 license, so there are no licensing headaches there either.
For image conversion you can go between JPG, PNG, WEBP, BMP, GIF, and TIFF — pretty much anything to anything. Max file size is 100MB. For video and audio (powered by FFmpeg), we support a wide range of formats: video formats include MP4, AVI, MOV, MKV, WEBM, FLV, and WMV; audio formats include MP3, WAV, AAC, FLAC, OGG, and M4A. You can convert video to video, video to audio, or audio to audio. Max media file size is 500MB. Note: video/audio conversion requires FFmpeg to be present on the server — the app will show you a warning if it's not available.
Yes — and I'm not going to pretend otherwise. I used Claude (an AI assistant by Anthropic) to help write a significant portion of the code. That said, I directed every decision: the architecture, the features, the design, what goes in and what doesn't. AI is a tool, and I used it the same way I'd use any other — to move faster and focus on the parts that actually matter. The ideas, the product vision, and every line I kept are mine. The result works, and I stand behind it.
