Resize images to exact pixel dimensions.
Resize an image online by entering the exact width and height in pixels. Keep the aspect ratio to avoid stretching, choose JPG, PNG, or WebP, and download the resized copy without uploading your image.
HOW IT WORKS
Exact dimensions, in three steps.
Enter pixel dimensions
Keep proportions to avoid stretching, or turn the option off for a custom shape.
Preview and download
Check the new dimensions and output format before saving your image.
CHOOSE THE RIGHT DIMENSIONS
Resize photos for websites, forms, and profiles
When a service asks for an image width and height in pixels, enter those exact dimensions here. Keep the aspect ratio checked to preserve the original proportions, or turn it off only when you intentionally need a different shape.
Fit a square crop area
Set equal width and height when the destination requires a square image. This tool resizes; it does not crop.
Use smaller dimensions
Reducing pixel dimensions can help make an image more suitable for web pages and upload limits.
Compress the result
Dimensions and file size are different. If the file must be under a KB limit, use the Fyloz image compressor after resizing.
QUICK ANSWERS
Image resizing FAQs
Does my image leave my device?
No. The browser processes the image locally; the file is not uploaded to Fyloz.
What does aspect ratio mean?
It is the relationship between width and height. Keeping it checked preserves the image proportions when you change one dimension.
Can I make an image larger?
Yes, but enlarging an image cannot restore detail that was not in the original and may make it look blurry.
Which output format should I choose?
JPG is useful for photos, PNG supports transparency, and WebP can offer smaller files. JPG output fills transparent areas with white.
