Why use Faster Image Converter
Private by design
Files never touch a server — nothing to leak.
No upload wait
Conversion starts the instant you select a file.
Works offline
Once loaded, keep converting without a connection.
Free, no account
No sign-up, no watermark, no artificial limits.
Your images are processed locally in your browser and never uploaded.
When you select a file, the converter reads it directly in memory using your browser's built-in CanvasAPI. Decoding, re-encoding, and generating the download all happen on your device — open your browser's network tab and confirm it yourself.
No storage
Files aren't written to disk or a database.
No content tracking
We don't inspect or log what's in your images.
You control the output
Converted files stay put until you download them.
Supported formats
More formats coming soon
JPG / JPEG
The standard photo format. Smaller size, no transparency.
PNG
Lossless, with full transparency support.
WebP
Modern format with strong compression.
BMP
Uncompressed bitmap, encoded natively — not relabeled.
Convert freely between any of these formats — for example, PNG to WebP, or BMP to JPG.
Frequently asked questions
Are my images really never uploaded?
Correct. Conversion happens entirely inside your browser using the Canvas API. No image data is sent over the network at any point.
What image formats are supported right now?
JPG/JPEG, PNG, WebP, and BMP, in any combination. Support for additional formats is planned for future updates.
Is there a limit on file size or how many images I can convert?
There's no artificial limit imposed by us. The practical limit is your device's available memory, since everything is processed locally.
Does this work on mobile devices?
Yes. The converter is fully responsive and uses standard browser APIs available on modern mobile browsers.
Why is my converted file sometimes larger than the original?
Different formats compress differently depending on the image content. Try WebP for the best balance of quality and size.
Is Faster Image Converter free to use?
Yes, entirely free, with no account or sign-up required.
