워터마크 없는 무료 HEIC 변환기 (2025 정리)
Many “free” HEIC converters add watermarks, limit file count, or require sign-up. Here are the ones that don’t.
What We Tested
We tested 8 popular HEIC converters on three criteria:
- No watermark — output must be clean
- No file limits — convert as many as you need
- No sign-up — start converting immediately
Results: The Good
| Converter | Watermark? | Limits? | EXIF? | Privacy? |
|---|---|---|---|---|
| heicgo.com | No | None | Yes | Local |
| HEICfree | No | None | No | Local |
| PicShift | No | None | No | Local |
| FreeConvert | No | 25/day | Yes | Upload |
| CloudConvert | No | 25/day | Yes | Upload |
Results: The Bad (Avoid These)
| Converter | Issue |
|---|---|
| HEICtoJPEG.app | Watermark on all outputs |
| Convertio | Requires account after 10 conversions |
| Online-Convert.com | Adds “converted by” footer text |
Why Watermarks Exist
Free converters add watermarks because:
- Server costs — HEIC conversion on a server uses CPU/GPU resources
- User acquisition — watermarks drive visitors back to their site
- Paid tiers — watermark removal is a premium feature
How heicgo.com Avoids Watermarks
heicgo processes everything in your browser using WebAssembly. There’s no server to pay for, so:
- No watermark needed
- No file count limits
- No sign-up required
- Supported by ads (Google AdSense)
The Privacy Angle
Upload-based converters (even watermark-free ones) have another cost: your data. Your photos sit on their servers during conversion. Client-side converters like heicgo keep everything local.
Try heicgo.com — free, no watermark, no upload.
