Frequently Asked Questions
+How do I resize an image without losing quality?
Use the quality slider at 85–100% and choose WebP or PNG output. WebP delivers the best file-size-to-quality ratio at the same resolution. Avoid upscaling — enlarging an image beyond its original size always reduces sharpness.
+Are my images stored on your servers?
Never. All processing happens in-memory on our server and the result is streamed directly back to your browser. Your image is not written to disk, logged, or retained after your download.
+What is the maximum file size for free users?
Free users can resize images up to 10 MB. Pro users get up to 50 MB per file and batch processing of up to 20 images at once.
+Which image formats are supported?
Input: JPG, PNG, and WebP. Output: JPG, PNG, or WebP — you can convert between formats in the same operation. For example, resize a PNG and save it as a smaller WebP in one step.
+What is the difference between JPG, PNG, and WebP output?
JPG is best for photos — small files, no transparency. PNG is lossless and preserves transparent backgrounds, ideal for logos and graphics. WebP is a modern format that offers smaller files than JPG at the same quality, with optional transparency support.
+Can I resize multiple images at once?
Batch resizing is a Pro feature. Free users process one image at a time. The Pro plan allows up to 20 images in a single batch upload.
+Does this work on iPhone and mobile devices?
Yes — the tool works in any modern browser with no installation required. Upload, resize options, and download all work on iPhone, Android, iPad, and any mobile browser including Safari on iOS.
+Is Image Resizer really free?
Yes. Resizing images up to 10 MB is completely free with no account and no credit card required. The Pro plan adds 50 MB file limits and batch processing of up to 20 images at once.
