AlphaTools

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.
