How to ASCII table

Find a character. Search by character, code, or name.
Read the codes. See its decimal, hex, and binary values.
Use it. Copy the value you need.

ASCII underpins text encoding, and a full table is invaluable when debugging why a byte is where it is or crafting escape sequences. Seeing decimal, hex, and binary together saves conversion.

For inspecting non-ASCII characters, use the Unicode inspector; for raw byte views, the hex/ASCII converter.

Frequently asked questions

What's the ASCII code for a space?

Decimal 32 (0x20). The table lists every printable character plus control codes like newline (10) and tab (9).

Does it include control characters?

Yes — the non-printable control codes (0–31) are included with their names, which is handy when debugging stray bytes.

Is anything fetched?

No. The table is built in and works offline.

Tool / area	Where work runs	Extra network
Merge, split, organize, protect	Browser + workers	App shell only
Compress, redact, clean	Browser + workers	App shell only
Export (PNG / JPEG / text)	Browser (pdf.js canvas)	App shell only
Forms, watermark, page #, insert	Browser (pdf-lib)	App shell only
OCR	Browser (pdf.js + Tesseract)	Same-origin WASM/worker/lang after postinstall (no third-party OCR CDN)
Duplicate scan (Organize)	Browser worker (pdf.js)	App shell only
Share Desk (P2P)	Browser WebRTC + OPFS worker	Signaling WebSocket + STUN (optional TURN) — no file bytes to SafePaper
Media Studio	Browser + FFmpeg WASM (lazy) + image workers	Same-origin FFmpeg under `/vendor/ffmpeg/`
Data Zone	Web Workers + DuckDB-wasm + OPFS queues	DuckDB bundles may fetch from jsDelivr on first SQL use — not your table rows
Security Vault	Browser Web Crypto + jose (no upload)	Analytics disabled on these routes
AI Desk (RAG)	Embedding + chat workers; IndexedDB index	One-time model weight downloads (Transformers.js / WebLLM CDN)
Record Desk	Capture + OPFS mux; Whisper worker	Whisper ONNX/WASM may fetch from jsDelivr on first caption run
Vision Studio	Image inference worker (ONNX / Transformers.js)	One-time model weight downloads (Hugging Face / jsDelivr); images stay local
Audio Lab	FFmpeg WASM worker + Web Audio; Whisper for transcription	One-time FFmpeg/Whisper asset downloads; audio samples stay local
Health Desk	dicom-parser + canvas; pure-JS HL7/FHIR; localStorage lab history	None — scans, records, and lab data are parsed and stored entirely on-device
Scan Desk	Camera + canvas image pipeline; Tesseract OCR; pdf-lib export	Same-origin OCR WASM/worker/lang only; scans stay on-device
Diagram Desk	Mermaid + Graphviz (WASM); canvas rasterize for export	One-time Graphviz WASM fetch; diagram source stays local
Handwriting Desk	Canvas render; MediaRecorder + FFmpeg WASM for video	Same-origin fonts + one-time FFmpeg assets; text stays local
Photo Desk	Canvas pixel ops; heic-to WASM decode; RAW preview parse	One-time HEIC WASM assets; photos are edited & encoded on-device
Resume Desk	@react-pdf render; pdf.js text extract; localStorage	App shell only; resume data stays in your browser's local storage
Email Desk	postal-mime / msgreader / TNEF parse; DOMPurify + sandboxed iframe (CSP blocks remote); @react-pdf render	App shell only; email files are parsed in your browser, remote images & trackers blocked by default
Password Desk	kdbxweb + hash-wasm Argon2; zxcvbn strength; otpauth TOTP; crypto.getRandomValues	App shell only; KeePass .kdbx vaults are decrypted & edited in your browser — master password never leaves the tab
Archive Desk	zip.js + fflate in archive worker	App shell only (central directory parsed locally)
Data Room	crypto-packager worker + offline HTML export	Same-origin `/dataroom-template.html` at build time
Storage Desk	Argon2id + AES-256-GCM crypto worker; OPFS + IndexedDB; on-device labeling/embeddings	None for Browser backend. BYO-S3 sends only opaque ciphertext straight to your own bucket (SigV4) — never to SafePaper
