Frequently asked questions
What is included in the result?
The result includes the image MIME type and Base64 data, ready to use as a data URL.
Does Base64 reduce image size?
No. Base64 text is typically larger than the original binary file.
Can I encode multiple images?
Choose one image per conversion so the result stays easy to copy and use.
Is the image uploaded?
No. The file is read locally and is never sent to a server.
What is the file size limit?
Images can be up to 25 MB; the resulting text can be substantially larger than the original file.
