Your input is processed locally in your browser whenever possible. We do not store your data.
Flow
- Validate the input format and surface precise parsing errors early.
- Apply the selected transformation entirely in your browser so raw input stays local.
- Return clean output with quick copy and reset actions for iterative testing.
Example
Worked example: image to base64 flow
- 1 Select a local PNG file in the input control.
- 2 Tool reads bytes and encodes them as Base64 plus optional data URI prefix.
- 3 Copy either raw Base64 or full data URI depending on your target usage.
Output is ready for inline embeds, JSON fixtures, or quick prototype assets.
How
- Select an image file from your device.
- The tool reads file bytes locally and encodes them to Base64.
- Copy either raw Base64 or the generated data URI output.
Cases
- Generate inline `data:image/...;base64,...` strings for quick prototypes.
- Create test fixtures for APIs that accept image payloads.
- Inspect image payload size before embedding in docs or config files.
Avoid
- Embedding very large images as Base64, which can bloat HTML/CSS files.
- Using the wrong MIME prefix for the selected image type.
- Assuming Base64 encoding reduces payload size (it usually increases size).
FAQ
Does image to base64 send my input to a server?
No. Image to Base64 handles the input in your browser whenever possible, so routine conversions, previews, and copy actions stay on your device instead of being sent to Calctrove servers.
Can I copy the output directly?
Yes, each tool provides copy actions for quick reuse.
What should I do if output looks wrong?
Verify file type, MIME prefix choice, and whether you copied raw Base64 vs full data URI output.
