Questions People Ask About OnlineToolsDesk

Do I need to install software or a browser extension?

No. All tools run in your browser on any device — Windows, Mac, Linux, Android, or iPhone. Chrome, Firefox, Safari, and Edge all work without any installation or extension.

What happens to files I upload?

Files are processed to produce your result and then deleted. They are never stored, indexed, shared, or used in any other way. For tools that work entirely in your browser without a server, the file never leaves your device at all.

How do I convert a PDF to Word for free?

Go to the PDF to Word converter, upload your file, click Convert, and download the editable .docx result. Most documents are ready in under a minute. Text-based PDFs convert with good accuracy. Scanned PDFs that are images of pages convert with less precision since the tool must interpret pixels rather than actual text.

How do I compress an image without losing quality?

Use the Image Compressor and set quality between 70 and 80 percent. At that setting the difference between original and compressed is not visible on any normal screen, while the file size drops by 50 to 75 percent. Quality loss only becomes clearly visible below 50 percent.

What is keyword density and what percentage should I use?

Keyword density is the percentage of times a word or phrase appears in your content relative to total word count. For most web content, keeping the primary keyword between 1 and 2 percent produces natural-reading text that covers the topic clearly. Use the Keyword Density Checker to measure this on any text or page.

What is the difference between PNG and WebP?

PNG is a lossless format that supports transparent backgrounds and has been the web standard for graphics and logos for decades. WebP is a newer format developed by Google that supports both lossy and lossless compression, handles transparency, and produces files roughly 25 to 35 percent smaller than PNG at the same visual quality. For web use today, WebP is generally the better choice. Use the PNG to WebP converter to switch.

How do I check if my website is mobile friendly?

Use the Mobile Friendly Test. Mobile usability is a confirmed Google ranking factor — pages that do not work well on phones rank lower in mobile search results, which now accounts for the majority of all searches globally.

How do I create a strong password?

Use the Password Generator to create a random password of at least 16 characters including uppercase, lowercase, numbers, and symbols. A randomly generated password is far stronger than anything a person would choose, because humans tend to use patterns that automated attacks can predict. After creating one, check it with the Password Strength Checker.

Why Use Browser-Based Tools Instead of Desktop Software?

The honest reason is convenience. Desktop software requires installation, takes up storage space, needs updates, and often only runs on one operating system. For tasks you do occasionally — converting a file, checking an SEO score, merging a few PDFs — the setup cost of dedicated software is not worth it.

Browser-based tools remove that friction. You find the tool when you need it, the task is done in the time it would have taken to open a desktop application, and you move on. The tradeoff is that browser tools have practical limits on file size and complexity. They are built for everyday tasks, not processing hundreds of files at once or handling specialized professional workflows that require advanced automation.

Every tool on OnlineToolsDesk is free, runs in your browser, and works on any device. If a tool is not working as expected, the Contact page is the right place to report it — and suggestions for new tools are always welcome.
