Frequently Asked Questions
Everything you need to know about resizing and compressing images with Resize4U.
Is my data safe? Do you store my photos?▼
100% safe. Resize4U works entirely in your browser using client-side JavaScript. Your images are never uploaded to any server, stored in any database, or seen by anyone else. You can even use this tool offline without an internet connection.
What is the best format for resizing images?▼
For photos and complex images, JPEG offers the best balance of quality and small file size. For logos, graphics, and images with transparency, use PNG. WebP is the modern standard that gives superior compression for both photos and graphics with full transparency support.
How do I resize an image to a specific file size (e.g., under 50KB)?▼
Upload your image, enter your target file size in the "Target File Size" box (e.g., 50 KB), and click "Resize & Compress". Resize4U will automatically adjust the image quality and dimensions to meet your exact requirement.
What DPI should I use for printing vs web?▼
For web, social media, and screen display, 72 or 96 DPI is standard. For high-quality printing (passport photos, documents, photo prints), use 300 DPI. For standard document printing, 150 DPI is sufficient.
Can I resize photos for official documents like passports and visas?▼
Yes! Use our built-in presets for US Passport (2x2 inches / 51x51mm), EU Passport (35x45mm), Indian Passport, Schengen Visa, and more. All presets automatically apply the correct 300 DPI print standard.
Is there a limit on how many images I can resize?▼
No limits at all. You can resize as many images as you want, anytime, completely free without creating an account or subscribing.
