PDF MergeCombine two or more PDFs into a single document, in the order you choose. Merging happens right in your browser, so your files never leave your device.
Split PDFPull pages out of a PDF or break it into several smaller files. Pick pages visually or type ranges — the file is processed on your device and never uploaded.
Compress PDFReduce the file size of a PDF with lossless optimisation, smaller images or full-page compression for scans — and see exactly how much each method saves. Your file never leaves your device.
PDF UnlockSave a copy of your PDF that opens without a password and has no printing or copying restrictions. You need to know the password — the file is decrypted in your browser and never uploaded.
PDF ProtectEncrypt a PDF so it can only be opened with your password, and optionally restrict printing, copying or editing. The encryption runs on your device — the file and password never leave it.
Rotate PDFFix sideways or upside-down pages and save the PDF with the correct orientation. Rotate everything at once or page by page — it all happens on your device.
Organize / Delete PagesSee every page of your PDF as a thumbnail, then drag to reorder, delete, duplicate or add blank pages. Everything runs on your device — nothing is uploaded.
JPG to PDFCombine photos, scans and screenshots into a single PDF in the order you choose. Conversion happens in your browser, so your images never leave your device.
PDF to JPGTurn every page of a PDF — or just the pages you pick — into JPG or PNG images. Pages are rendered in your browser, so the document never leaves your device.
PDF Page NumbersStamp page numbers onto any PDF in the position and style you want, with a live preview of the result. Everything happens in your browser — your document isn’t uploaded.
Add Watermark to PDFMark a PDF as CONFIDENTIAL, DRAFT or with your logo — on every page or only the pages you pick. The watermark is applied in your browser, so your file is never uploaded.
Sign PDFAdd your signature and the date to any page of a PDF by drawing, typing or uploading it, then drag it into place. Everything runs in your browser — the document never leaves your device.
Repair PDFTry to recover a PDF that won't open or shows errors. The tool checks the file structure, rebuilds it cleanly and tells you how many pages it got back — all on your device.

Image Tools

Image CompressorShrink JPG, PNG and WebP files for websites, email and forms — up to 50 at once. Compression runs on your device, so your photos are never uploaded.

JSON FormatterPaste messy or minified JSON to get clean, indented output instantly — or minify it for production. Sort keys, browse a collapsible tree and see exactly where any error is.
JSON ValidatorCheck whether your JSON is valid and get the exact line, column and reason for any error. One click repairs common mistakes like trailing commas, single quotes and comments.

JWT DecoderPaste a JSON Web Token to read its header and claims, see whether it's expired, and optionally verify the signature with a secret or public key — all without the token leaving your browser.

CSV to JSONPaste CSV or open a file to get clean JSON — an array of objects or arrays — with proper handling of quotes, line breaks, delimiters and data types. Large files up to 10 MB+ work too.
JSON to CSVTurn JSON arrays into a CSV you can open in Excel or Google Sheets. Nested objects become columns like address.city, and every value is quoted correctly.

Website Tools

Open category →
Password GeneratorCreate truly random passwords and easy-to-type passphrases right in your browser. See how strong each one is in bits of entropy and estimated time to crack.
Password Strength CheckerSee how long your password would really take to crack. The checker looks for the patterns attackers try first — common passwords, words, keyboard walks, dates — and runs entirely in your browser.
DNS LookupQuery a domain's DNS records live from a public resolver of your choice. See every record type at once, with TTLs, mail servers in priority order and email-authentication records highlighted.
IP LookupFind out who an IP address belongs to. Enter an IPv4 or IPv6 address — or a domain — to see its network owner, ASN, routing prefix, registry details and reverse DNS.
HTTP Header CheckerSee the exact status code and response headers a URL returns, follow its redirects, and get a security-header grade with clear fixes.
SSL CheckerTest a site's SSL/TLS certificate in seconds: see when it expires, whether browsers trust it, if it matches the domain, and which TLS versions the server still allows.
Redirect CheckerFollow a URL hop by hop and see every redirect's status code, destination, server and timing — plus clear advice on chains, loops and SEO-safe redirect types.
HTTP Status Code LookupLook up any HTTP status code to see what it means, why it happens, how to fix it and how it affects SEO — including unofficial codes from Cloudflare, nginx and others.
My IP AddressYour public IP address is shown below the moment the page loads, together with your internet provider, approximate location and what your browser reveals about you.
DNS Propagation CheckerChanged a DNS record? Ask 19 public DNS resolvers in the US, Europe and Asia at once and see which ones already return the new value.
Website Status CheckerFind out in seconds whether a site is up, answering with errors, or down — and why, from DNS through to the server's response.
Website Uptime CheckerRun a quick series of checks against a site to see how reliably and how fast it answers right now — handy for spotting intermittent outages and slow spikes.
Ping ExplainerBrowsers can't send ping packets, so run ping yourself and paste the result here — we'll chart it and explain exactly what every line means.
Traceroute ExplainerRun traceroute on your computer, paste the result, and get a hop-by-hop table with a plain-English read of where delays and timeouts really matter.
Reverse DNS LookupTurn IP addresses back into hostnames. We look up each address's PTR record and check that the hostname points back to the same IP — the forward-confirmed reverse DNS test mail servers rely on.
Security Headers CheckerFind out which HTTP security headers a site sends, how strong they are and exactly what to add. Every header gets a clear verdict and a copy-ready value, plus config for your server.
SPF DMARC DKIM CheckerTest how well a domain is protected against email spoofing. We read its SPF, DKIM, DMARC, MX and BIMI records live, explain every problem and give you the exact DNS records to fix it.
