Frequently Asked Questions
Is this tool completely free?
Yes! File Gulp provides completely free file conversion tools with no hidden fees, no watermarks, and no registration required.
Are my files safe?
Absolutely. Unlike other converters, File Gulp uses modern WebAssembly technology to convert files directly on your device. Your files never leave your computer, ensuring maximum privacy.
Does it work on mobile devices?
Yes, our tool is fully responsive and works perfectly on smartphones and tablets, directly from your mobile browser.
Will the quality be affected?
No, we use high-quality algorithms to ensure your output files maintain the best possible quality during conversion.
Is there a file size limit?
Very large files may be limited by your device memory/browser performance. For normal image sizes, conversion is fast and seamless.
Understanding Aspect Ratios
An aspect ratio is the proportional relationship between an image's width and height. For example, 1:1 is a perfect square used for Instagram profiles. 16:9 is the standard widescreen format used for YouTube thumbnails and modern TVs, while 4:3 is common for standard photography.
Private Client-Side Cropping
Uploading personal photos to an online tool can be a massive privacy risk. File Gulp uses native Canvas HTML5 technology to process and crop your images directly inside your web browser. Your files are entirely secure and are never transferred over the internet.
Why use a dedicated local cropper?
While many OS built-in viewers offer basic crop features, a dedicated web tool provides specific advantages for professionals and casual users alike:
- Precision Ratios: Force your crop to fit exact social media requirements (like 9:16 for Reels or TikTok) with one click.
- Format Control: Export as WebP for smaller files, strip transparency by converting to JPG, or maintain maximum quality by keeping it as a PNG file.
- No Quality Degradation: Because the tool does not send the file to a server and back, there's no chance for an automated server script to forcefully lower your image quality.
