Sack of HacksUseful little internet tools

A VERY SMALL, VERY USEFUL TOOLBOX

Meet your new favorite hacks.

Three oddly specific problems.
Three tools that get the hint.

01DOCUMENT RESCUE
THE FIXER
READY WHEN YOU ARE

PDF CLEANER ADVANCED

Scans looking like they were faxed from a cave?

Give them a little sunlight. Clean up the noise, straighten the page, and make that mystery smudge someone else’s problem.

Clean up a PDF

No account needed. Your paperwork can stay mysterious.

THE SERIOUS BIT

Make every page pull its weight.

  • 01Adjust contrast, brightness, sharpness, and noise.
  • 02Auto-enhance, deskew, rotate, crop, or clear an area.
  • 03Preview changes, undo edits, reorder pages, and export.
  • 04Remove shadows from unevenly lit scans.

Untouched pages keep their original content. Edited pages are rasterized.

02MERCH DEPARTMENT
THE MAKER
READY WHEN YOU ARE

LOGO PRINT PREP

Your logo called. It wants to be a sticker.

Turn a humble image into a tiny merch empire. Get transparent, print-sized files for shirts, hoodies, mugs, caps, and stickers—without learning what DPI stands for first.

Prep a logo

One upload. Five print-ready-ish starting points.

THE SERIOUS BIT

From one image to four formats.

  • 01Detect transparent pixels or remove a simple edge-connected background.
  • 02Keep the design’s proportions on product-sized transparent canvases.
  • 03Check dimensions, DPI, transparency, and color count; download a ZIP report.

Background removal works best with a plain, even background.

03LINK DEPARTMENT
THE CONNECTOR
READY WHEN YOU ARE

QR CODE MAKER

Got a link? Give it a little square-shaped shortcut.

Make QR codes for links, Wi-Fi, contacts, and messages. Pick a color style, then save a crisp PNG or scalable SVG—no account, no fuss.

Make a QR code

Made in your browser. Your text stays yours.

THE SERIOUS BIT

A tiny square with places to go.

  • 01Make link, Wi-Fi, vCard, email, phone, or SMS codes.
  • 02Choose screen, print, or forest-and-cream styles; contrast warnings help keep codes scannable.
  • 03Download a PNG or SVG with a quiet zone, or copy the PNG image.

For reliable scanning, keep strong contrast between the code and its background.
