ASCII85 Encoder API

GET

Pack data into more compact ASCII text than standard Base64.

ASCII85 Encoder encodes text into Base85 strings or decodes existing ASCII85 payloads back to plain text. Each request returns the converted output with original and processed character counts, while paid plans add custom formats and compression ratios.

About the ASCII85 Encoder API

ASCII85 Encoder works by converting binary data to ASCII text using base-85 encoding, which represents 4 bytes with 5 ASCII characters. Includes special handling for zero bytes and format delimiters.

What people use it for

Data Encoding
Encode binary data for text-based transmission with better compression than Base64
PDF Processing
Handle ASCII85-encoded data in PDF files and PostScript documents
Data Serialization
Serialize binary data for storage in text-based formats like JSON or XML
Compression
Achieve better compression ratios for binary data in text-only protocols

Questions.

Common questions about the ASCII85 Encoder API.

Read the docs →
How many conversions does the Free plan cover?
The Free plan covers 100 conversions each month using its 200 included credits. If your volume grows, the Starter plan provides 100,000 conversions per month, which works out to about $0.30 per 1,000 calls.
Can I check the compression ratio on the Free plan?
No. The compression ratio and format fields are premium features unlocked on paid plans. Free tier requests return the original text, converted string, and character length measurements.
Does the encoder support the btoa Base85 variation?
Yes, on paid plans. ASCII85 Encoder supports both standard Base85 and the btoa format variant. You can encode plain strings into either standard or decode existing payloads back to their original form.
How does the encoder handle runs of zero bytes?
The service implements standard Base85 rules for zero-byte runs and delimiter characters. It maps every four bytes of source data into five printable ASCII characters while handling zero-value sequences cleanly.
Are custom format parameters permitted on the Free plan?
Specifying a custom format parameter is restricted to paid subscriptions. On the Free plan, requests run using default formatting, and the format field is omitted from the JSON response.
