Exam Age CalculatorEnter your date of birth and pick an exam to see your exact age on its cut-off date and whether you're within the age limit for your category. Or choose any date to simply calculate your age as on that day.
CGPA to Percentage ConverterEvery board and university converts CGPA to percentage its own way, and many websites use the wrong formula. Pick yours: the converter uses the formula from its official regulations or circular and links to that document.
Attendance CalculatorEnter the classes held so far and how many you attended. You'll see your attendance now, how many classes you can still miss without dropping below 75% (or any percentage you set), or how many you must attend in a row to get back above it.
Marks Percentage CalculatorType the marks you got and the maximum for each subject. The total and percentage update as you type, and you can also see the percentage of your best three to six subjects for forms that ask for it.
SGPA & CGPA CalculatorWork out your SGPA for a semester from each course's credits and grade, or your CGPA from your semester SGPAs. Letter grades follow the UGC 10-point scale, and you can type grade points directly if your university uses a different table.

Signature MakerDraw a signature with your mouse or finger, or upload a photo of one signed on paper. Save it as a JPG that meets an exam form's pixel and KB limits, or as a transparent PNG.
Name & Date on PhotoSome application forms want the candidate's name and the date the photo was taken printed under the face. Crop your photo, type both, and download a JPG that meets the form's limits.
Passport Photo SheetCrop your photo to passport size once, and get a print-ready sheet with as many copies as fit, with cutting guides. Download it as a 300 DPI JPG or as a PDF at the exact paper size.
PDF CompressorMake PDFs smaller on your device, or fit them under a portal's limit such as 100 KB. Keep text re-saves only the photos and scans inside the PDF, so text stays selectable; Maximum turns every page into a JPG for the smallest scans.
