Easy Centering Tool for TCG

"Could not detect the card." "Take it out of the sleeve." "Create an account first." "My saved measurements are gone." This app was built to answer those four. ■ You place the corners, so it always measures It does look for the card automatically, but only to put the handles somewhere sensible. You set the four corners yourself, so "it won't detect my card" simply cannot happen. ■ Shoot from any angle. Same numbers. The tilt is removed from the four corners and the card's real dimensions before anything is measured. No need to reshoot from directly above. It works through a sleeve. ■ See which side holds it back Colour marks whether the left/right or the top/bottom border is the one setting your ceiling. ■ No predictions. Just the ceiling. It returns how far centering alone could take a card — nothing more. Edges, corners and surface are not measured, so a real grade will land at or below what you see here. This app does not predict grades. ■ No photo? Type the numbers. Enter the four border widths from calipers or a ruler and you get the same answer. ■ Front and back Grading companies apply a different tolerance to the back. Measure both and the ceiling gets more accurate. ■ Stays on your phone Photos and records never leave the device. No account. No limit on how many times you measure. Everything exports in one file. FREE, ALWAYS - Unlimited measurements - Front and back - Both card sizes (63x88 / 59x86 mm) - Grading standards tables and the ceiling - Viewing every record you already saved - Backup export and import PRO (ONE-TIME PURCHASE) - Unlimited saves to the album (20 without Pro) - Filter by "10 candidates" and "suits ARS" - Export result images without a watermark - CSV export - Custom card sizes No monthly or yearly subscription.

Your PDF is ready. Then the upload form says: file too large. Maybe it needs to be under 10 MB. Or 2 MB. Or even 500 KB. You don't want to learn compression settings, and you definitely don't want to keep guessing—compress, check the size, try again, compress again. You just need the PDF to fit. That's what PDF Under is built for. Tell it the MB or KB you need, and it works toward exactly that number. But making a PDF smaller is only half the problem. It still has to look like your PDF. Some compression methods shrink a file by turning every page into a picture—smaller, yes, but the text is no longer selectable, and the document never quite looks right again. PDF Under does it differently. Whenever possible, it keeps your text and vector content untouched, and compresses only the embedded images that were taking up the space in the first place. Smaller file. Same document. You choose the number. 500 KB, 1 MB, 2 MB, 5 MB, 10 MB, or a custom target of your own—no "low, medium, high" guessing games, just the size you were actually asked for. And before you save or share anything, you see the result first: the final size, the finished pages, exactly what you're about to send. Where does this happen? On your phone. Not on a server somewhere. Your PDF is never uploaded, which matters more than usual when the document you're shrinking is the one you'd rather not hand to a random compression website in the first place. No account. No sign-in. Just your file, compressed, still yours. Now, the honest part. Not every target is reachable. A fifty-page scanned document doesn't become 500 KB without something giving—that's just how file size and image quality work, and PDF Under won't pretend otherwise. When your target is more aggressive than the document can survive, it tells you plainly, shows you the smallest version that's still readable, and lets you decide from there. No silent damage. No surprises when you open the file later. This is the app for the moment a portal, a form, an inbox, or a government website hands you a number and expects you to hit it—job applications, school submissions, legal filings, an email that keeps bouncing back because the attachment is too big. Select the PDF, set the target, compress, check the result, send it. Five steps, and you're done. PDF Under is free to try—your first three compressions cost nothing. After that, a Weekly, Yearly, or Lifetime plan unlocks unlimited use, so you're never stuck mid-deadline wondering if today's the day you run out. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends, and you can manage or cancel anytime in your Apple Account settings. Full pricing is shown in the app before you're asked to pay anything. Because when a website tells you your PDF is too large, you shouldn't have to become a compression expert just to send a document. You should just be able to get it under the limit.
