Frequently Asked Questions
Everything you need to know about our privacy-first, client-side tools, browser support, and file limits.
🔒 Privacy & Security
Are my files really safe? Do they ever get uploaded to your servers?
They are 100% private and safe. ToolBox Web is engineered with a strict zero-upload architecture. When you compress an image, merge PDFs, or format JSON, all data processing takes place directly inside your own web browser’s memory using client-side JavaScript, Web Cryptography, and the HTML5 Canvas API. Your files never touch our servers or any cloud storage.
Does ToolBox Web store my generated passwords or scanned QR codes?
No. Generated passwords and decoded QR codes exist only in your browser tab's volatile runtime memory. We do not maintain any databases, logs, or analytics that record your inputs. Once you close the tab or refresh the page, the data disappears completely.
Is ToolBox Web compliant with GDPR and CCPA regulations?
Yes. Because we do not collect, process, or store personal files or personally identifiable information (PII), we exceed standard compliance mandates. Our only persistent first-party storage is a single entry in your browser's localStorage storing your preferred visual theme (light or dark mode).
📄 Image & PDF Tools
What is the maximum file size I can compress or merge?
Because all processing happens on your local device, file size limitations are governed by your device's available RAM and browser hardware acceleration rather than artificial server quotas. Most modern computers and smartphones can effortlessly handle images up to 50MB and PDF files containing hundreds of pages.
Why is image compression and resizing so much faster than other websites?
Traditional conversion websites force you to upload your multi-megabyte image over the internet, wait in a backend server queue, and then download the converted file. ToolBox Web eliminates network latency entirely by rasterizing and re-encoding the image directly on your local GPU/CPU in a fraction of a second.
What image formats are supported for conversion?
Our Image Converter natively supports JPEG, PNG, and modern WebP. You can easily convert between any of these formats with adjustable compression qualities.
⚡ Technology & Compatibility
Can I use ToolBox Web while offline without an internet connection?
Tools process data locally after the page and required libraries have loaded. PDF and QR tools initially download libraries from third-party CDNs. Reopening or reloading pages offline is not guaranteed to work.
Which browsers and devices are supported?
ToolBox Web is fully responsive and optimized for all modern evergreen browsers, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Opera, and Brave, across desktop, laptop, tablet, and mobile platforms.
Are there any paid subscriptions, limits, or API keys required?
None whatsoever. All 20 utilities are 100% free and open to everyone without signups, account registrations, subscriptions, or API keys.
