IMAGE RESIZE GUIDE
Practical criteria for accurate resizing
Mixed landscape and portrait images can be resized consistently by pixels, percentage, long edge, or short edge. Evaluate the output by its actual dimensions and aspect ratio before focusing on file size.Scale from the original
Use one ratio such as 25%, 50%, or 150% across a batch.
Mixed-orientation batches
Keep landscape and portrait images consistent without treating orientation separately.
PRACTICAL DETAILS
What to verify in real use
Aspect ratio
Locked by default to prevent stretching or squashing.
Upscaling protection
Smaller images keep their original dimensions unless enlargement is explicitly allowed.
Expected dimensions
Each file shows its predicted output dimensions before processing.
Format preservation
JPG remains JPG, PNG remains PNG, and WebP remains WebP.
Long edge versus short edge
Long edge targets the larger side; short edge targets the smaller side. This is useful when landscape and portrait images are mixed.
Upscaling is not restoration
Increasing pixel dimensions does not recreate missing detail. Check edges and sharpness in the final destination.
Photo, graphics, and pixel art
Photos need smooth gradients, graphics need clean edges, and pixel art needs preserved pixel boundaries.
Resizing versus compression
Reducing pixels often lowers file size, but does not guarantee a specific KB or MB target. Use a compression tool when file size itself is the requirement.
FAQ
Frequently asked questions
01Does this only reduce file size?+
This tool changes pixel dimensions. File size often decreases when pixel count is reduced, but a specific KB or MB value is not guaranteed.
02Can I resize multiple images to the same rule?+
Yes. Apply one pixel, percentage, long-edge, or short-edge rule to all files, or customize files individually.
03Can landscape and portrait images be processed together?+
Yes. Long-edge and short-edge modes apply the same rule regardless of orientation.
04What does Keep Aspect Ratio mean?+
It preserves the original width-to-height relationship so the image is not stretched or squashed.
05Can I make an image exactly 1200×800 px?+
Yes, by unlocking aspect ratio, but the image can be distorted when the source ratio differs.
