No. You can use all FlowFix tools immediately without creating an account, signing in, or providing any personal information. Simply open a tool page and start processing your files right away.

Question 4

What browsers does FlowFix support?

Accepted Answer

FlowFix works on all modern web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera. We recommend using the latest version of your browser for the best experience. Our tools also work on mobile browsers for smartphones and tablets.

Question 5

Can I use FlowFix on my phone or tablet?

Accepted Answer

Yes. FlowFix is fully responsive and works on any device with a modern web browser. Whether you are on an Android phone, iPhone, iPad, or any other tablet, you can access and use all tools without any limitations.

Question 6

Are my files uploaded to your servers?

Accepted Answer

No. This is one of the most important things about FlowFix. All file processing happens entirely within your web browser using client-side JavaScript. Your files never leave your device. They are not uploaded, stored, or transmitted to any external server. When you close the browser tab, all data is gone.

Question 7

Is it safe to process sensitive documents?

Accepted Answer

Absolutely. Because FlowFix processes everything locally in your browser, there is no risk of data interception, server breaches, or unauthorized access. You can safely process confidential contracts, financial statements, personal photos, and any other sensitive material.

Question 8

Do you collect any personal data?

Accepted Answer

We do not collect or store any personal data from your file processing activities. Our website uses standard analytics cookies to understand traffic patterns and improve the user experience. You can read our full Privacy Policy for detailed information.

Question 9

How is FlowFix different from other online tools?

Accepted Answer

Most online PDF and image tools require you to upload your files to their servers for processing. This creates privacy risks and depends on your internet speed. FlowFix is different because all processing happens locally in your browser, which means faster results, complete privacy, and no file size limitations imposed by upload speeds.

Question 10

What is the maximum PDF file size I can process?

Accepted Answer

Most PDF tools support files up to 20MB. This covers the vast majority of standard business documents, academic papers, and scanned files. For very large files, we recommend splitting them into smaller sections first using our Split PDF tool.

Question 11

Can I merge more than two PDFs at once?

Accepted Answer

Yes. Our Merge PDF tool allows you to combine up to 10 PDF files in a single operation. You can drag and drop to reorder the files before merging, ensuring your final document has the exact page sequence you need.

Question 12

Does the PDF compression reduce quality?

Accepted Answer

Our PDF compressor is designed to reduce file size while maintaining readable quality. For most documents containing primarily text and standard graphics, the quality reduction is minimal. You can preview the compression results before downloading to ensure the output meets your standards.

Question 13

Can I edit the text inside a PDF?

Accepted Answer

Our PDF Editor allows you to annotate, highlight, draw, add text boxes, and place sticky notes on PDF documents. For modifying the original text content of a PDF, you would typically need the source document in an editable format like Word or Google Docs.

Question 14

What does the Terms Scanner tool do?

Accepted Answer

The Terms and Conditions Scanner analyzes legal documents and highlights potentially concerning clauses such as data sharing with third parties, automatic renewal fees, forced arbitration, non-refundable terms, and broad content licensing. It helps you quickly understand what you are agreeing to before signing up for services.

Question 15

What image formats does FlowFix support?

Accepted Answer

Our image tools support all major web formats including JPG/JPEG, PNG, WEBP, GIF, and BMP. You can freely convert between these formats using our Convert Image tool. The specific formats available may vary slightly between tools.

Question 16

Can I compress multiple images at once?

Accepted Answer

Yes. Our Compress Image tool supports batch processing of up to 25 images simultaneously. All compressed files are packaged into a convenient ZIP download, making it easy to handle large collections of photos or website assets.

Question 17

What is the best image format for websites?

Accepted Answer

WEBP is currently the best format for web images because it offers superior compression at equivalent visual quality compared to JPG and PNG. Most modern browsers support WEBP natively. For images that require transparency, PNG or WEBP are the best choices. You can use our Convert Image tool to switch between formats easily.

Question 18

How does the Image to Base64 tool work?

Accepted Answer

The Image to Base64 tool converts your image file into a text string that can be embedded directly into HTML, CSS, or JavaScript code. This is useful for small icons and graphics (under 10KB) because it eliminates the need for separate HTTP requests, improving page load speed. The tool generates a complete Data URI that you can copy and paste into your code.

Question 19

What dimensions should I use for social media images?

Accepted Answer

Common recommended sizes include 1080x1080 pixels for Instagram posts, 1200x627 for LinkedIn and Facebook shared images, 1280x720 for YouTube thumbnails, and 1000x1500 for Pinterest pins. Our Resize Image tool makes it easy to adjust your images to these exact specifications.

Question 20

Why is FlowFix so fast?

Accepted Answer

FlowFix processes files using your device's own processing power through modern browser technologies like WebAssembly, the Canvas API, and JavaScript. Because there is no upload or download step, the processing starts immediately and completes in seconds. The speed depends on your device's hardware, but even mid-range computers and phones handle most operations very quickly.

Question 21

Does FlowFix work offline?

Accepted Answer

You need an internet connection to initially load the tool pages. However, once a tool page is loaded in your browser, the actual file processing does not require an active internet connection because everything runs locally. If your internet connection drops mid-processing, your work will not be affected.

Question 22

What technologies does FlowFix use?

Accepted Answer

FlowFix is built with Next.js and uses industry-standard open-source libraries for file processing. PDF operations use pdf-lib and PDF.js, while image operations leverage the HTML5 Canvas API and native browser capabilities. These trusted, battle-tested libraries ensure reliable and accurate results.
