How to resize images without stretching
- Choose your images. Add a batch of supported files.
- Choose the longest side. Use a preset or enter a custom value under Image size. A landscape image uses this for its width, and a portrait image for its height.
- Choose the format and convert. The result shows its new width and height. Download each image or the batch ZIP.
For example, a 4,000 × 3,000 image becomes 1,920 × 1,440 at the 1,920-pixel setting. A 3,000 × 4,000 portrait becomes 1,440 × 1,920. This tool keeps proportions, does not crop and never enlarges smaller originals.
Dimensions alone do not guarantee a smaller file. Try a maximum file size if an upload form has a KB limit. For transparent graphics, choose PNG, WebP or AVIF.

A few useful details.
Choose your images, pick a format, and download the results. No account needed by the converter.
Which image formats can I convert?
Open JPG, PNG, WebP, HEIC, TIFF, AVIF, GIF, BMP, ICO, and self-contained SVG. Save as JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, or ICO. HEIC export and vector tracing are not available. See the full format guide.
Will I lose quality or transparency?
PNG keeps pixel detail without lossy compression. JPG, WebP, and AVIF use the quality setting. JPG, GIF, BMP, and TIFF outputs fill transparency with your chosen background. Resizing can lose detail. Existing compression artifacts cannot be undone.
What happens to animation and metadata?
Animated inputs become a single still frame. EXIF, GPS, source DPI, and other original metadata are not copied. This version is designed for everyday screen images, not color-critical printing or animation preservation.
Are there file size limits?
Up to 20 files, 100 MB per file, and 250 MB combined. Originals can be up to 120 megapixels and 65,535 pixels per side. Automatic size reduces large images to an output within 32 megapixels and 8,192 pixels per side. Smaller images keep their dimensions. Very large files may still exceed your device’s available memory. Closing or refreshing the page clears the queue.
