YOUR WORKSPACE
Resize image width and height free online, preserve proportions when needed and process photo batches. Preview dimensions and avoid stretching or expecting lost detail to return.
The sample is 1200 × 800 pixels. Keep the aspect ratio and set width to 600. Height becomes 400 and the exported image is 600 × 400 pixels.
Inputs up to 30 MB and outputs up to 40 million pixels. Enlarging cannot restore detail missing from the original. JPEG does not preserve transparency.
Keep aspect ratio enabled. To change the composition, crop first and resize afterwards.
No. Process and preview first, then download when satisfied.
Use this tool for free without a KitNelo account. Processing runs in your browser; input limits, browser support and device memory still apply.
Enlarging a low-resolution photo cannot restore missing detail. Independent width and height changes can distort proportions.
Read KitNelo data and privacy detailsChoose an image and enter the output width and height required by your destination. Check the resulting dimensions and preview before downloading; changing both values independently can alter the original proportions and visibly stretch the subject.
Keep the original proportions while selecting the new photo dimensions, then review the preview for distortion. Enlarging a small source can produce a bigger file but cannot restore missing detail, so inspect sharpness at the intended display size.
Add the photos that need new dimensions and apply the available batch resize settings. Review the exported sizes and proportions for each original, particularly when the batch mixes portrait and landscape images with different starting dimensions.
