2048 Beer
A familiar merging puzzle with a beer-inspired visual identity.
Use arrow keys or swipe to combine matching tiles, progressing from Fresh Pour to Legendary Brew. Wooden textures, illustrated glasses, and increasingly dark tile colors give each upgrade a distinct look.
- Three modes: Standard, Classic, and Plus.
- Standard includes Undo, Swap, and Clear one; Classic keeps the puzzle free of power-ups.
- Play with a keyboard or touch controls, directly in your browser.
BingoMint
Turn an activity idea into a stack of printable bingo cards.
A card-making workspace for classrooms, parties, and group activities. Add words, pictures, and emoji; adjust the design; preview the result; then generate different arrangements and print-ready PDFs.
- Custom 3×3, 4×4, and 5×5 cards, plus classic 30-, 75-, 80-, and 90-ball formats.
- Theme templates, free spaces, card styling, and A4 or Letter layouts.
- Six-ticket 90-ball strips, local saving and JSON backups, plus a local caller and card check.
- Basic creation and downloads need no account, with a multilingual interface.

Catalog Precheck
Understand product-file problems before importing into a store.
A browser-based workspace for bulk catalog tasks. Check Shopify CSV/XLSX structure, headers, products, variants, prices, and image URLs, with findings tied to specific records and fields.

- File checks run in your browser. Review the findings before choosing whether to download a modified copy.

VZTool
Small tools, made useful.
A family of tools for image creation, everyday design, and smaller files. The main site helps you discover tools, while 6 dedicated subdomains each offer a focused workspace. File processing stays in your browser.
| Tool | What it does | Dedicated site |
|---|---|---|
| Image to ASCII | Turn images and animations into character art | ascii.vztool.com |
| Icon Workshop | Create icons from images or text | icon.vztool.com |
| Pixel Studio | Create pixel art, animations, and craft patterns | pixel.vztool.com |
| GridSplit | Split social-media grids and preview posting order | split.vztool.com |
| Cutout | Remove backgrounds with AI and refine by hand | cutout.vztool.com |
| Compress | Make videos, images, and PDFs smaller | compress.vztool.com |
Image to ASCII
Convert photos into character art, adjusting characters, colors, and detail while previewing the result. Export text, PNG, SVG, HTML, or ANSI for avatars, posters, and terminal-inspired artwork.
GIF and animated WebP inputs keep their frame timing and loops when exported as GIF. Still-image and text exports use the first frame.
Icon Workshop
Turn an image or text into website favicons and app icons. Preview different sizes and shapes, then download ICO, PNG, or an icon pack with a manifest and installation code for your project.
Pixel Studio
Convert photos into pixel art, controlling the look through grid density, color count, and preset palettes. Export the artwork or create numbered patterns for a craft project.
Convert GIF and animated WebP inputs into animated pixel art and download GIF. PNG, craft guides, and ZIP exports use the first frame.
GridSplit
Split a larger image into a social-media grid. Preview the full composition in a profile layout, review tile numbers and posting order, and download the pieces as a package.
Cutout
Remove backgrounds with AI, then refine edges with a lasso, magic wand, or brush. Switch between subject and background, soften edges, replace the background, and undo edits before exporting transparent PNG, JPG, or a mask.
Batch cutout handles up to 10 images, with individual transparent PNGs or a ZIP download. Dedicated workspaces cover white backgrounds, product photos, portraits, and stickers.
Images stay on your device. AI mode downloads its model on first use, and availability depends on your browser and hardware.
Compress
Smaller videos, images, and PDFs, processed on your device.
Choose a target size in KB or MB, or adjust quality to suit your file. Compare the result and download a separate copy without uploading the original or creating an account.
- Video compression for MP4, MOV, and WebM, with optional trimming; format support depends on your browser.
- JPG, PNG, WebP, and animated GIF compression, with common size presets and dimension controls.
- PDF compression optimizes document structure and embedded images while preserving text and vectors. Signed and encrypted PDFs are not supported.
Output size and quality depend on the source file; a target size is not guaranteed.
