Base64 Encoder / Decoder for scanned documents specifically
Scanned strings come out unnecessarily huge by default. Base64 Encoder / Decoder brings them down dramatically without losing the text.
If you've ended up here, you have a string and a specific job: scanned document. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.
Run it in your browser: Base64 Encoder / Decoder — No upload, no signup, no daily limit.
Why scanned document needs different settings
A string for scanned document optimises for things the original string doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.
The workflow with Base64 Encoder / Decoder
- Open Base64 Encoder / Decoder in any modern browser.
- Drop the string on the input area.
- Choose settings appropriate for scanned document — see the recommendations in the next section.
- Run the processing. It happens locally in your browser tab.
- Download and verify. Quick visual check before you send.
Recommended settings for scanned document
Scanned strings are notorious for size bloat. The right move is to keep the text crisp while aggressively compressing the surrounding white space and the embedded thumbnail. Base64 Encoder / Decoder handles both in a single pass.
Launch the tool
Browser-only. Nothing is sent to a server.
What to verify before sending
Quick check-list once Base64 Encoder / Decoder finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
What if the recipient asks for the original?
Keep the original. Base64 Encoder / Decoder produces a copy; the source file you dragged in is never modified.
Does compressing a string make it look unprofessional for scanned document?
Not when done right. Sensible compression at the "balanced" preset produces output indistinguishable from the original to the human eye, even at half the size.
Is Base64 Encoder / Decoder safe for sensitive strings like a resume or visa documents?
Yes — every step happens locally in your browser. The string never leaves your device because there is no server in the loop.
Can I undo the compression later?
No — compression is one-way. Always keep the original string archived somewhere, and treat the compressed version as a send-only copy.
