About
AlphaTools is a set of online tools that work right in your browser, with no install and no sign-up. It is split into four services: time tools, file conversion, calculators with developer tools, and card grading prediction.
AlphaTimer
A countdown timer, a Pomodoro timer and a stopwatch. The alarm rings on time even when you are in another tab, the time left shows in the tab title, and a timer you set can be shared by link.
AlphaConverter
Convert images (JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO, HEIC), PDFs (merge, split, rotate, compress, sign, edit, password), Korean HWP and Word, Excel and PowerPoint documents, Markdown and HTML, and audio and video (MP3, MP4, GIF, WebM), and read the text in pictures. Add a file and it works out the type and shows the formats it can become. Conversion happens inside your browser, so files never leave your device, there is no upload to wait for, and the site sets no size or file-count limit.
AlphaKit
Currency, unit, date, age, loan and compound-interest calculators, developer tools such as JSON, Base64, hashes and regular expressions, and text tools such as a word counter and text diff. Everything is calculated on this device; only exchange rates are downloaded, updated a few times a day.
AlphaGrade
Measures the centering of a trading card precisely from front and back photos, finds whitening on the corners and edges, and shows estimated PSA, CGC, BGS and TAG grades. Photos are analyzed only on this device.
AlphaPick
AlphaPick is a set of drawing tools. Each name becomes a marble, and the finishing order decides first place, last place, the Nth finisher or teams. It has 7 maps with portals, items and random events, live captions and sound, video recording and result cards, and the names you enter never leave your browser.
What we aim for
- It should work as soon as you open it The tool is at the top of the page and asks for no sign-up or install.
- What you enter stays on your device Files and inputs are processed only inside your browser.
- It should be accurate Time does not drift while you use another tab, and calculators show the basis they use.
