Frequently Asked Questions (FAQ)
1. How do I resize my photo for the UPSC or SSC exam portal?
Indian competitive exams like UPSC and SSC have strict KB limits (usually 20KB to 50KB). To achieve this, upload your photo to our Image Compressor. Adjust the quality slider until the file size matches the requirement. Always export as JPG, as government portals rarely accept PNG or WebP.
2. Is PixelExchanger safe for uploading my ID cards?
Absolutely. We use "Client-Side Processing." This means when you select an image, it stays within your browser's memory. It is not uploaded to our servers. This makes PixelExchanger the safest choice for sensitive documents like Aadhar, Voter ID, or Marksheets.
3. Why should I use WebP instead of JPG for my blog?
WebP is a modern format developed by Google that provides superior compression. A WebP image is usually 30% smaller than a JPG of the same quality. For global creators, this means your website will rank better on Google because it loads faster for your users.
4. My iPhone saves photos as HEIC. How can I upload them to a form?
Most websites do not support HEIC yet. Use our HEIC to JPG tool. Simply drop your iPhone photos there, and we will instantly convert them to JPG so you can upload them to any college or job application portal.
5. Can I add multiple images into one PDF?
Yes! Our Image to PDF tool allows you to select multiple scans (like your 10th and 12th certificates) and merge them into a single, professional PDF document, which is a common requirement for postgraduate admissions (GATE/CAT).
6. Will my edited images have a watermark?
No. We believe in providing value to the student community and global users. All exports are clean, high-resolution, and completely free of any PixelExchanger branding or watermarks.
7. What is the benefit of the 'Contrast' slider for scanned documents?
When you scan a signature with a mobile phone, the background often looks grey. By increasing the contrast and slightly bumping the brightness, you can make the background white and the ink black, ensuring your signature isn't rejected by exam automated systems.
8. Does this tool work on mobile phones?
Yes, PixelExchanger is fully responsive. You can edit your photos directly on your Android or iOS device without downloading any bulky apps from the Play Store.
9. Can I convert a PNG logo to SVG?
Our PNG to SVG tool creates a vector container for your image. While it won't make a low-res image "infinitely" sharp, it allows designers to use your logo in vector software like Figma or Adobe Illustrator more easily.
10. How many images can I edit per day?
There are no limits. Whether you have 1 image or 100, you can process them all for free. We support the "Unlimited Access" philosophy to help students who may be applying to dozens of different universities.
11. What is the "Hue Rotate" feature used for?
Hue Rotate shifts all the colors in your image. It’s mostly used for creative projects or social media filters to change the mood of a photo (e.g., turning a blue sky into a purple sci-fi landscape).
12. Why is my image blurry after resizing?
If you try to make a very small image much larger, "pixelation" occurs. To avoid this, always start with a high-resolution photo. If you are shrinking a photo for an exam, it will remain sharp as long as you use our optimized resizer.
13. Does PixelExchanger support TIFF files?
Yes, you can export your edited work as a TIFF file, which is often used in high-quality print publishing and professional photography workflows due to its lossless nature.
14. What are the recommended dimensions for a YouTube Thumbnail?
For a perfect YouTube thumbnail, use our Thumbnail Maker. The ideal size is 1280x720 pixels with a 16:9 aspect ratio. Our tool ensures your file stays under the 2MB limit required by YouTube.
15. Do I need an internet connection to use the tool?
You need a connection to load the website initially. However, since the actual image processing happens in your browser's local environment, the editing process is extremely fast even on slower "2G/3G" connections often found in rural parts of India.
