Fast, no-nonsense tools and calculators that run entirely in your browser. Type a number or drop in a file, get an answer — nothing is uploaded, nothing is stored.
These numbers never leave this page. Full tip calculator →
Nothing matches that. Try “tax”, “paint”, “grade”, “HEIC” or “tabs”.
Build a professional PDF invoice and download it — no account, no watermark, no limit. Your client's name and your bank details never leave your browser.
Make an invoice FreeName the size you're allowed — under 2 MB for the application form, under 500 KB for the upload that keeps failing — and it finds the best quality that fits. Nothing is uploaded.
Compress an image FreeMakes static codes — ones that can never expire or be deactivated, unlike the "free" dynamic codes most generators hand out. URL, WiFi, contact card, email and SMS, with PNG and SVG download.
Make a QR code FreeWindows can't open your iPhone photos because the decoder costs money. This one doesn't — convert a whole camera roll to JPG at full resolution, keeping the date taken. Nothing is uploaded.
Convert HEIC photos FreeYour photos quietly carry the time, the camera and often the exact coordinates of where you stood. See all of it — then download a clean copy with every trace cut out.
Check a photo FreeSee when a video was really recorded — not when the file was copied — and find out why it won't play. Reads the file in your browser; nothing is uploaded.
Check a video FreeBlack bars that delete the pixels underneath instead of covering them — no layer anyone can drag away, and no pixelation that can be read back.
Redact a screenshot FreeThe form wants 600 × 600 and you have a phone photo. Say the number and get the number — crop to fill, pad to fit, or rescale a whole folder at once.
Resize an image FreeSquare, 4:5, 16:9 or your own ratio — and you choose which part survives, rather than letting the platform crop your photo wherever it likes.
Crop an image FreeOne image into every icon a site needs — ICO, Apple touch, Android, manifest and the HTML to paste — with an honest 16-pixel preview in a mock tab.
Make a favicon FreeYou saved an image from a website and got a .webp that Photoshop won't open and the form won't accept. Turn it into an ordinary JPG at full resolution. Also handles AVIF.
Convert a WebP FreeEvery other PDF merger wants the file first. This one has no server to upload to — combine documents, reorder them, take just the pages you need. No watermark, no limit.
Merge PDFs FreeSend the four pages they asked for, not your whole bank statement. Extract pages, or break a scanned bundle back into separate documents. Nothing is uploaded.
Split a PDF FreePhone photos of a signed form into one PDF, fitted to A4 or Letter. No quality thrown away — your JPGs go in exactly as they are.
Make a PDF FreeYour PDF names you, your software and your time zone, and carries an ID linking it to your other files. See all of it — then take a copy with none of it.
