QR Bundles
A collection of QR codes saved in one place — like a shortlist you can reopen, reorder, and share as a single .qrb file. Scan furniture in a store, share with family for opinions, then come back to the bundle anytime.
NxtTools: All-in-One Utility
NxtTools is the only mobile app with QR Bundles, plus QR and document scanner and complete PDF, DOC, Image, and Sign utilities in one place. Replace app-hopping with one fast, clean toolkit built for everyday tasks.
An all-in-one mobile toolkit, built for everyday tasks
On-device
Every tool runs locally on your phone. No cloud round-trip.
No sign-up
Install, open, and use. No account required for any documented tool.
No watermark
Clean exports — no NxtTools brand stamped on your scans or PDFs.
No daily cap
Scan, compress, and sign as many files as you want. No trial countdown.
An all-in-one mobile toolkit, built for everyday tasks
NxtTools is the all-in-one mobile utility app from Const Agility, LLC in Houston, Texas. One install gives you a document scanner, full PDF tools (compress, merge, split, rotate, export), image tools, a signature pad, a document viewer, a file manager, and the QR Bundle feature that turns a handful of links into one shareable .qrb file.
Every tool ships free, runs on-device by default, requires no sign-up, and never stamps a watermark on your output. The reward-ad backend tier and an upcoming AI tier are separate; nothing on this page asks you to pay or sign in.
What people do with NxtTools
Six everyday workflows that used to need five apps and a desktop.
Scan a receipt and email it
Capture the receipt, auto-crop edges, save as a clean PDF, and send it to your accountant — without leaving the app or watching an ad.
Sign a contract from your phone
Open the PDF, drop your saved signature anywhere on the page, save the signed copy, and email it back. No DocuSign account, no per-signature charge.
Build a QR Bundle for retail, real estate, or events
Group product pages, listing photos, event schedules, or sponsor links into one .qrb file. Share one QR code instead of ten.
Compress a PDF to fit email limits
Cut a 30 MB scan down to under 5 MB in two taps so Gmail and Outlook attachments actually go through.
Resize and sign a photo in seconds
Crop, rotate, resize, or watermark an image, drop your signature on top, save it, and share — all on the phone you already have.
Keep every file in one place
Filter by PDF, image, scan, signature, or document. Open, share, print, or delete with one tap — no folder spelunking.
NxtTools vs. the typical mobile workflow
Five small frictions add up. NxtTools fixes them in one install.
Typical mobile workflow
Five different apps for scanning, signing, compressing, resizing, and managing files.
Two or three monthly subscriptions to unlock the features you actually need.
Free tiers stamp a watermark on every export until you pay.
Files upload to a third-party cloud before they're processed.
Account sign-up and email verification before you can compress a single PDF.
With NxtTools
One install covers scan, sign, compress, resize, and file manager — same UI, same place.
Free for every tool documented on this page. No subscription tier hidden behind the workflow.
Clean output every time. No watermark, no "made with X" footer.
Every tool processes locally on your device. The file never leaves your phone.
Install and use. No account required for any of the documented tools.

Document Scanner
Turn your phone into a portable scanner. Capture receipts, forms, notes, and IDs as clean digital files and save them as PDF or images.
PDF Tools
Compress, grayscale, monochrome, enhance, extract pages, or export as images. Create PDFs from multiple files and merge them — then download, share, or print in a tap.
Image Tools
View, compress, rotate, flip, crop, resize, and enhance images. Overlay your signature and save the result.
Document Viewer
Open Word, Excel, PowerPoint, CSV, RTF, and ODF files from your device or a link. Export any of them to PDF in one tap.
Digital Signatures
Draw or type your signature with multiple fonts and colors. Save it once, then apply it anywhere — to PDFs, images, or your workflow.
Audio & Video Player
Play local audio and video files or open them from a URL. No extra player app needed.
File Manager
Everything you save stays in one place. Filter by type — PDF, images, documents, scans, signatures — then open, share, print, or delete with a tap.

Frequently asked questions
The fast answers to the questions everyone asks first.
- What does NxtTools actually do?
- NxtTools is an all-in-one mobile utility app. One install gives you a document scanner, PDF tools (compress, merge, split, rotate, extract pages, export as images), image tools, a signature pad, a document viewer for Word/Excel/PowerPoint/CSV/RTF/ODF files, a file manager, and the QR Bundle feature for grouping links into one shareable .qrb file.
- Is NxtTools really free?
- Yes. Every tool documented on this page is free with no sign-up, no watermark, no daily cap. A reward-ad backend tier and an upcoming AI tier are separate; nothing required for the everyday on-device toolkit costs money.
- Does NxtTools work offline?
- Yes for the on-device toolkit. Scanning, PDF compression, signature placement, image editing, and file management all run locally on your phone — no internet required. Only backend features (the reward-ad tier and the upcoming AI features) need a connection.
- Do I need to create an account?
- No. Install the app from the App Store or Google Play and start using every documented tool. Account sign-in (Apple, Google, or email) is only requested when you opt into backend features.
- Is there a desktop or web version?
- Not yet. NxtTools is mobile-first today: iPhone and iPad on the App Store, Android on Google Play, and the iPad app runs natively on Apple Silicon Macs (M1 and up) via the Mac App Store. A web version is on the roadmap.
- How is NxtTools different from other PDF or scanner apps?
- Most mobile PDF or scanner apps are single-purpose and ad-supported, watermark your exports, or push you to a subscription to unlock anything useful. NxtTools bundles a scanner, full PDF tools, image tools, a signature pad, a file manager, and QR Bundles into one free install — on-device, no watermark, no sign-up, no daily cap.
