Image Tool Hub FAQ

Find detailed answers to common questions about Image Tool Hub, our free online media processing tools, and how to get the most out of the platform.

What is Image Tool Hub?

Image Tool Hub is a free online platform with over 100 on-device tools for processing images, videos, audio files, PDFs, and Word documents, with no watermarks on outputs. We offer format conversion, compression, resizing, cropping, merging, editing, and many other utilities across image, video, audio, PDF, Word, and text categories.

Is Image Tool Hub really free?

Yes. Every tool is free to use, with no hidden fees. An optional Pro plan raises the free plan's limits, such as file size and batch processing. We fund the platform through non-intrusive advertising (e.g., Google AdSense). You can use our tools as often as you like for personal or commercial purposes. We do not add watermarks to processed files.

Do I need to create an account?

No. The free tools work without an account: open the tool you need, select or drag-and-drop your files, adjust settings if required, and process. An account is only needed if you subscribe to Pro.

Are my files uploaded to your servers?

No. All file processing occurs entirely on your device, not our servers. We do not have access to your files, and we do not store them on our servers. This local-only approach is a core design principle of Image Tool Hub and ensures maximum privacy and security for your data.

What file formats does Image Tool Hub support?

We support a wide range of formats. Images: JPG/JPEG, PNG, WebP, GIF, AVIF, BMP. Videos: MP4, WebM, MOV, GIF. Audio: MP3, WAV, OGG, AAC, M4A, FLAC. Documents: PDF, DOCX (Word). Support varies by tool—for example, our image converter supports conversions between JPG, PNG, WebP, GIF, AVIF, and BMP. Our video converter handles MP4, WebM, MOV, and GIF. Check the specific tool page for the formats it supports.

What is the maximum file size I can process?

Each tool shows its own limit. On the free plan, images can be up to 25 MB and 4,096 px, and videos up to 100 MB, 5 minutes, and 720p; Pro lifts these caps. Because files are processed on your device, very large files also depend on its memory (RAM), so close other tabs and applications when processing them. If you run into out-of-memory errors, try smaller batches or a device with more RAM.

Which browsers are supported?

Image Tool Hub works best in modern browsers: Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge. We recommend using the latest version of your browser for the best performance and compatibility. Some tools rely on newer browser capabilities for video processing that may not be available in older browsers. Mobile browsers are supported for many tools, though complex operations (e.g., large video processing) may perform better on desktop. We do not support Internet Explorer.

Can I use Image Tool Hub for commercial purposes?

Yes. You may use Image Tool Hub for personal or commercial purposes. However, the service is provided 'as is' without warranties. You are responsible for ensuring you have the legal right to process any content you use, and for verifying that results meet your requirements. We recommend testing outputs before using them in production or critical applications. See our Terms of Use and Disclaimer for full details.

How does on-device processing work?

On-device processing means all the work is done on your computer, tablet, or phone, not our servers. When you use a tool, your file is read, processed (e.g., converted, compressed, resized), and the output is produced right there on your device. This keeps your files private and often gives fast results, since there is no upload or download delay.

Why did my processing fail or produce unexpected results?

Several factors can affect results: (1) File format or corruption—ensure your file is valid and in a supported format. (2) Browser compatibility—try a different or updated browser. (3) Device resources—large files may cause timeouts or out-of-memory errors on low-RAM devices. (4) Settings—check that you have configured the tool correctly (e.g., quality, dimensions). (5) Browser extensions—some ad blockers or privacy extensions can interfere. If problems persist, try in an incognito/private window or contact us with details (browser, device, file type, and error message).

Do you add watermarks to processed files?

No. We do not add watermarks, logos, or any branding to your processed files. The output you download is exactly what the tool produces based on your input and settings. The only exception would be tools designed to add watermarks (e.g., our Image Watermark or Video Watermark tools), where you control the watermark content and placement.

How do you protect my privacy?

We protect your privacy by processing your files on your device, not our servers. We do not collect, store, or have access to your file content. We may collect minimal usage data (e.g., anonymous analytics, cookies) for website operation and improvement. You can control non-essential cookies via our cookie banner. We do not sell your personal information. For full details, see our Privacy Policy and Cookie Policy.

What happens if I process copyrighted content?

You are responsible for ensuring you have the legal right to process any content you use. Processing copyrighted material without authorization may violate copyright law. Image Tool Hub does not monitor the content you process and is not responsible for user conduct. If you believe content on our website infringes your copyright, see our DMCA Policy for how to file a takedown notice. Users who repeatedly infringe copyright may have their access terminated.

Can I process multiple files at once?

Yes, with Pro: batch processing lets you select or drag several files and process them in one go, while the free plan processes one file at a time on most tools. Tools whose input is several files, like the PDF and audio mergers, accept multiple files on both plans. Check the tool page for its limits. For very large batches, consider processing in smaller groups to avoid running out of memory.

How do I get support or report a bug?

Use our Contact page to send a message. Include as much detail as possible: which tool you used, your browser and device, what you expected vs. what happened, and any error messages. We read all submissions and respond as quickly as we can. For common questions, check this FAQ first. We also welcome feedback and feature suggestions.

Does Image Tool Hub work on mobile?

Yes. Many of our tools work on mobile browsers (Chrome, Safari, Firefox on iOS and Android). However, processing large files or complex operations may be slower or may fail on devices with limited memory. For best results with heavy tasks (e.g., video compression, batch image processing), we recommend using a desktop or laptop. Mobile is ideal for quick conversions and smaller files.

What image formats can I convert between?

Our image format converter supports conversions between JPG/JPEG, PNG, WebP, GIF, AVIF, and BMP. You can convert from any of these formats to any other. We also have format-specific compressors (e.g., JPG Compressor, PNG Compressor, WebP Compressor) and an All-in-One Converter that handles multiple formats. AVIF is a modern format offering excellent compression; WebP is widely supported and efficient.

What video formats are supported?

We support MP4, WebM, MOV, and GIF for video. Our video format converter allows conversions between these formats. We also have format-specific compressors (MP4, WebM, MOV) and mergers. MP4 (H.264) is the most widely compatible; WebM (VP9) offers good compression; MOV is common on Apple devices; GIF is used for short animated clips.

How do I compress a PDF?

Use our PDF Compressor tool. Add your PDF, and the tool will reduce its file size by compressing images and optimizing the document structure. It all runs on your device, not our servers. You can then download the compressed version. For best results, ensure your original PDF is not already heavily compressed.

Is there a limit on how many times I can use the tools?

No. You can use our tools as many times as you like. The free plan limits the size of each file and, on most tools, processes one file at a time; Pro raises those limits. Beyond that, very large files depend on your device's performance and memory.
