Fit a wide photo
- Input or situation
- Original 2400 × 1600 pixels; target width 1200 with aspect ratio locked
- Result
- 1200 × 800 pixels
Both dimensions scale by one half, preserving the original 3:2 proportions.

Image Resizer: Change Width, Height or Percentage
Resize a picture by width, height or percentage, or fit it inside a box. Keep its proportions and check the new dimensions before downloading.

Supported formats and export details
Open: JPG/JPEG, PNG/APNG, WebP, HEIC/HEIF, AVIF, TIFF, BMP, GIF, ICO/CUR, SVG, PSD/PSB, TGA, JPEG XL, JPEG 2000, QOI, PPM/PGM/PBM/PNM/PAM, PCX, DDS, HDR and EXR.
Save: JPG, PNG, WebP, AVIF, TIFF, BMP, still GIF, ICO, JPEG XL, JPEG 2000, TGA and QOI.
HEIC is input-only. Camera RAW, PDF, EPS and AI documents are not supported here. Unusual variants or damaged files may not decode. Files up to 80 MB and images up to 64 megapixels are accepted, but your device may run out of memory sooner.
Each export is one flattened still image with 8-bit sRGB pixels. Animated images use the first frame, multipage files use the first page, and Photoshop files use their saved composite. SVG uses the drawing’s intrinsic dimensions; linked images and external fonts are not loaded. Original files are never modified. ICO fits the picture inside a square up to 256 pixels. Extract GIF frames or convert PDF pages when you need the other frames or pages.

How to use
- Open a picture. Choose one or several images. Select a file in the workspace to preview it.
- Pick how to resize. Use Width or Height for an exact side, Percentage for proportional scaling, or Fit inside a box for a maximum width and height.
- Keep proportions and choose a format. Aspect ratio is preserved. Enlargement is off by default; enable it only if you need larger dimensions. Choose the output format before downloading.
- Preview and download. Check the actual output dimensions and file size, compare with the original, then download the selected image or all images in one ZIP.
Questions
How do I resize without stretching?
Every resize mode preserves aspect ratio. Setting width calculates height automatically; fitting inside a box keeps the whole picture inside both limits. Use Crop if you need to change the shape of the image.
Can I make an image larger?
Yes, by enabling Allow enlargement. Resampling adds pixels but cannot restore missing detail. Enlargement is disabled by default so a small original is not silently made larger.
Does resizing change print resolution?
This tool controls pixel dimensions, not a print shop’s physical-size or DPI workflow. Check the required pixel dimensions with your printer, and retain the original for colour-critical or high-bit-depth work.
Can I convert several images at once?
Yes. Add several files, select one to preview, and use Prepare all as ZIP, then Save ZIP. The current format, quality, resizing, crop percentages and rotation apply to every image. Duplicate filenames receive a numbered suffix; failures are reported separately. Smaller batches are easier on a phone’s memory.
What happens to animation, layers and metadata?
This workspace exports one flattened still image with 8-bit sRGB pixels. It uses the first frame of an animation, the first page of a multipage image and the saved composite of a Photoshop file. Camera and location metadata are removed. Keep the original for animation, layers, high-bit-depth editing or colour-critical work.
Are my pictures uploaded?
No. Decoding, editing and conversion run on your device. The image processor downloads from ToolsNow the first time you open a picture; your files are not sent to a server. Keep the page open to continue editing without uploading.
Examples and checks
Resize an image for a known destination, such as a page layout or upload limit. Pixel dimensions determine the detail available; changing a DPI label alone does not create more detail.
Before you use the result
- Aspect ratio stays fixed during resizing. Crop first when the destination needs a different shape.
- Enlarging a small image interpolates existing pixels. It does not recover detail that was absent from the original.
