Each file can be up to 20MB, and you can convert up to 5 files at once (100MB total per batch). Need to convert more? Just run another batch — there's no daily limit on how many conversions you can do.

Most conversions finish in just a few seconds. Larger files or complex formats like video may take a bit longer, but our cloud-based processing keeps things fast. You'll see real-time progress so you know exactly when your file is ready.

It depends on the formats involved. Converting between lossless formats (like PNG to BMP) preserves full quality. When converting to compressed formats (like JPEG or MP3), some quality reduction is normal but usually unnoticeable. For best results, we recommend keeping your original files and using the highest quality settings available.
