Frequently asked questions
Can I resize multiple files together?
Yes. Choose up to ten images; each uses the same dimensions or percentage and is processed sequentially.
Can I resize by percentage?
Yes. Choose Percentage and enter a scale from 1% to 500%.
What presets are included?
Instagram post (1080 × 1080), YouTube thumbnail (1280 × 720), and passport photo (413 × 531). The aspect lock fits the source inside the target.
How does aspect lock work?
When enabled, the output fits within the requested width and height without stretching the image.
Can I enlarge an image?
Yes. Enlarging cannot restore detail that was not present in the source.
Are my images sent to a server?
No. The image is resized locally in a browser worker and is never uploaded.
What size limits apply?
Each input is limited to 25 MB; output is limited to 16,000 pixels per side and 80 megapixels.
