Frequently Asked Questions
Can I resize multiple images that have different aspect ratios?
Yes. You can use the "Max Bounds" mode (e.g. 1920×1080) or "By Percentage" mode (e.g. 50%). Each image scales down proportionally according to its individual aspect ratio without any stretching or deformation.
How does Aspect Ratio Lock work with exact pixel dimensions?
When Aspect Ratio Lock is enabled in Exact Dimensions mode, setting your desired Width will automatically calculate the matching Height for each individual photo so proportions remain intact.
Can I change the format of my images during bulk resize?
Yes. You can preserve the original format or convert the entire batch into JPG, PNG, or WebP with configurable compression quality.
Is there a limit on how many images I can resize?
Because SizeSnap performs all processing directly inside your browser memory with zero upload delays, you can process dozens of photos smoothly on modern mobile phones, laptops, and PCs.
