Resize Image Online
Resize by pixels, centimeters or percentage — lock aspect ratio, pick a format and target a file size.
Good to know
- Keep “Lock proportions” on to avoid stretching.
- Use centimeters with DPI for print-ready output.
- Target a file size in KB or MB — JPG and WebP adjust quality to hit it.
About the Image Resizer
The PPRPress Image Resizer lets you change any picture to the exact size you need using three modes: pixels for screen work, centimeters (with a DPI setting) for print-ready output, and percentage for quick scaling. Keep “Lock proportions” on and the other dimension updates automatically so your image is never stretched or squashed.
You can also choose the output format — JPG, PNG or WebP — and target a specific file size in KB or MB. For JPG and WebP, PPRPress adjusts the export quality to land at or below your target size; for PNG (lossless) it keeps the best quality and explains when an exact size cannot be guaranteed. Everything runs in your browser, so your images stay private and the result is ready instantly.
Frequently asked questions
- How do I resize an image to specific dimensions?
- Add your image, choose “Pixels”, enter the target width or height, and PPRPress fills in the other dimension to keep the aspect ratio. Click Resize and download the result.
- Can I resize by centimeters for printing?
- Yes. Choose “Dimensions (cm)”, enter the width and/or height in centimeters, and set the DPI (default 300). PPRPress converts centimeters to pixels using that resolution.
- Can I scale an image by percentage?
- Yes. Choose “Percentage” and use the slider or type a value. 100% keeps the original size, 50% halves it and 200% doubles it.
- Can I make the output a specific file size?
- Yes. Set “Target file size” to KB or MB and enter the desired size. For JPG and WebP, PPRPress adjusts quality to reach that size. PNG is lossless, so an exact size cannot be guaranteed — switch to JPG or WebP for size targeting.
- Will resizing distort my image?
- No. With “Lock proportions” on, PPRPress adjusts the other dimension automatically, so the image keeps its original proportions in every mode.
- How do I resize an image to a specific size in pixels?
- Add your image, enter the width and height in pixels and download the resized copy. You can also resize by centimeters or percentage.
- Can I resize an image to a target file size in KB?
- Yes. PPRPress can aim for a target file size, which is handy for forms and uploads that have a size limit.
