Resize an image by pixels or percentage
Choose an image, enter a width and height or a percentage, then select the output format. Keep proportions on when changing the width to avoid stretching.
For example, reducing a 2,000 px-wide image to 1,000 px makes it half as wide. Lower dimensions often reduce file size, but the chosen format and quality also affect the download.
JPEG and WebP quality settings can reduce file size; PNG is lossless and does not use the quality setting. Results may be larger than the original, so compare the displayed sizes. Re-encoding removes most metadata and preserves only the first frame of animated WebP files. JPEG replaces transparency with your chosen background.
Common image questions
Why is the output larger than my original?
The original may already be compressed efficiently. Dimensions, format and quality all affect file size. Compare the displayed sizes, and try JPEG or WebP if suitable for your image.
What if my file will not open?
Use JPEG, PNG or WebP within the limits shown by the tool. Renaming a file extension does not convert it. Try one smaller file if a large batch fails; your browser may not have enough memory.
Where is my processed image?
After processing, use the download link in the results. Check your browser’s download list or your phone’s Files app. Processing on this page does not save your images to a BZ WorkOps account.
