Free trial - lossless compression

Try the Orchestrator
byte-exact lossless compression.

Run T15 Orchestrator free, through the REST API and the CLI. Compress real files and get them back byte-for-byte: every restore is SHA-256-verified, and the output carries a +1 byte never-worse floor. No credit card to start.

input -> orchestrate (SRD math + codecs) -> smallest verified .pdli -> restore -> SHA-256 match

LESS WEIGHT - SAME BYTES - VERIFIED RESTORE

Start the free trial -> See what you get

No credit card to start - every result restores the original byte-for-byte, or it stays proof-only / diagnostic.

What the trial is

A real trial of the compression API and CLI.

The free trial gives you working access to T15 Orchestrator over the same two surfaces you would use in production - the REST API and the command-line tool - so you can compress your own data, restore it, and confirm the SHA-256 roundtrip yourself.

API REST endpoint

Compress over the REST API

Send bytes, get back a restorable .pdli container. Restore and verify in one round trip. Wire it into a pipeline with a trial token.

# compress over the trial API
curl -X POST https://pedulli.io/api/compress \
  -H "Authorization: Bearer $PDLI_TRIAL_TOKEN" \
  --data-binary @data.json -o data.pdli

# restore - SHA-256 of output must match the original
curl -X POST https://pedulli.io/api/decompress \
  -H "Authorization: Bearer $PDLI_TRIAL_TOKEN" \
  --data-binary @data.pdli -o data.json
CLI Command line

Compress from the CLI

Single files or whole folders. The CLI runs the same orchestration and prints the verified result, including the SHA-256 match on restore.

# compress a file or a folder
pdli compress ./project -o project.pdli

# restore and verify byte-for-byte
pdli restore project.pdli -o ./project-out
pdli verify project.pdli   # SHA-256 roundtrip: PASS

What you get

Everything you need to prove it on your own data.

The trial is not a watered-down demo. It is the real Orchestrator with the same three guarantees - byte-exact, SHA-256-verified, and a +1 byte never-worse floor - applied to whatever you feed it.

01

Trial API token

A token for the REST API so you can compress and restore over HTTP straight from your own code or shell.

02

The CLI binary

The command-line tool for Windows, macOS and Linux - compress, restore and verify files and folders locally.

03

Byte-exact restore

Lossless, byte-for-byte. What you put in is exactly what comes back - no lossy re-encode, no approximation.

04

SHA-256 verification

Every output is roundtripped and the restored bytes must SHA-256-match the original, or it is not shipped.

05

+1 byte never-worse floor

Never larger than the best standard codec (worst case +1 byte). No fake savings on random or already-compressed data.

06

All filetypes, folders, any size

Raw-byte entry point handles any format; whole folder trees compress to one container; large inputs stream in bounded memory.

COMPRESS

input -> SRD math + codecs -> smallest verified .pdli

ROUNDTRIP

RESTORE

file.pdli -> inverse -> original bytes (SHA-256 match)

Trial scope

Same engine. Sensible trial limits.

The trial runs the real Orchestrator with the same guarantees. The only differences are usage limits, so you can evaluate before you commit.

In the free trial
  • REST API access with a trial token
  • CLI for Windows, macOS and Linux
  • Byte-exact, SHA-256-verified restore on every run
  • +1 byte never-worse floor
  • All filetypes, folders and streaming for large inputs
  • Capped monthly volume and request rate
When you upgrade
  • Higher volume and request limits
  • The advisory surfaces for planning runs (recommend engine, savings.estimate, codec.compare, noexpansion.explain, integration.plan, ratio.predict)
  • Production tokens and integration support
  • SLA and priority handling

How to start

Three steps to your first verified .pdli.

STEP 01

Sign up

Create an account - no credit card. Your trial API token and CLI download are issued immediately.

STEP 02

Compress your data

Use the API or CLI on a real file or folder. The Orchestrator keeps the smallest verified output.

STEP 03

Restore and verify

Restore the .pdli and confirm the SHA-256 of the output matches the original byte-for-byte.

FAQ

Trial questions

Do I need a credit card to start?
No. Sign up and your trial API token and CLI download are issued right away. You only enter billing details if you choose to upgrade later.
Is the trial the real Orchestrator?
Yes. It is the same engine with the same three guarantees - byte-exact, SHA-256-verified restore, and the +1 byte never-worse floor. The only differences are usage limits.
What can I compress during the trial?
All filetypes (the entry point is raw bytes), whole folders / directory trees, and large inputs via streaming in bounded memory, up to the trial volume cap.
How do I know restore is byte-exact?
Every output is roundtripped and the restored bytes must SHA-256-match the original. The CLI prints the result of pdli verify, and the API returns the verification status. If it does not match, the result is not shipped.
What happens with already-compressed or encrypted files?
They take the proof-only path: exact restore is preserved and no compression win is claimed. Random or incompressible input is never presented as savings - the +1 byte never-worse floor holds.
Where do the advisory and planning surfaces live?
The advisory surfaces - recommend engine, savings.estimate, codec.compare, noexpansion.explain, integration.plan, ratio.predict - are part of the Orchestrator product and unlock when you upgrade. See the Orchestrator overview and pricing.

Compress it. Verify it. Ship it.

Start the free trial, run the API or CLI on your own data, and confirm the SHA-256 roundtrip yourself. Then see the measured numbers.
