About the formats
JPG
JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.
Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.
PNG
PNG is a lossless raster image format created in the mid-1990s as a patent-free replacement for GIF. It is the standard choice for screenshots, logos, UI graphics, and any image that needs transparency.
PNG preserves every pixel exactly and supports a full 8-bit alpha channel, so text and sharp edges stay crisp. The downside is size: photographs saved as PNG are far larger than the same image as JPG or WebP. Support is universal in browsers and editors, making it a safe default for graphics — just avoid it for large photo collections.
WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.
Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.
Privacy and file handling
Processing happens in your browser, so the selected file is not uploaded.
- Browser-local processing
- The conversion runs on this device after the page loads.
- No file upload
- The source image does not need to leave your browser.
- No model API
- This basic tool does not send the file to an AI model.
Resize Image troubleshooting
- The image did not get bigger
- Larger dimensions are allowed, but ordinary resizing cannot invent real detail. If the result looks soft, start from a higher-resolution source.
- How are exact dimensions produced?
- The visual editor always exports the exact width and height shown. If a downloaded file differs, reset the editor and enter the values again before converting.
- The resized photo looks slightly softer than the original
- Downscaling resamples the pixels and re-encodes the file in its original format, so very large reductions can soften fine detail. Resize once, directly from the highest-resolution original, instead of shrinking in several passes.
FAQ
- Will resizing stretch my image?
- No. The image fills the target frame proportionally; when ratios differ, the live preview shows the cropped area.
- Is the conversion private?
- Yes. Resizing runs locally in your browser, so the image never leaves your device.
- Is there a file size limit?
- Free accounts can upload files up to 50 MB. Paid users can upload up to 200 MB.
- Can I enlarge a small image?
- Yes, but ordinary resizing cannot invent new detail, so large enlargements may look soft.
- Will the output match the exact width and height I entered?
- Yes. The downloaded image uses the exact width and height shown in the editor.
- Which formats are supported?
- JPG, PNG and WebP. The output keeps the same format as your source image.
- Does resizing count against the anonymous free limit?
- No. Single-file resizing runs in your browser and does not use a server conversion.
