How to Use the Image Converter & Resizer
- Drag and drop an image into the upload zone, or click Choose File to browse your device. PNG, JPG, WEBP, GIF, SVG, BMP and ICO are all supported.
- Pick an output format in the Format Output panel. For JPG or WEBP, use the quality slider to balance sharpness against file size.
- Either type an exact Width × Height with the lock toggle to keep proportions, or choose a Social Presets option to auto-fill the correct dimensions for a platform.
- Choose a resize mode: Stretch forces the exact size, Fit scales the whole image in with padding, and Cover scales up and crops the center to fill the frame edge-to-edge.
- Check the crop overlay and live result preview, then click Convert & Download to save the finished file — everything happens locally in your browser.
Supported Image Converter Formats
Input Formats
- PNG
- Lossless, supports transparency. Best for graphics, logos, and screenshots.
- JPG / JPEG
- Lossy compression, no transparency. Best for photographs.
- WEBP
- Modern format with strong compression; supports transparency and animation.
- GIF
- Supports simple animation and transparency; processing captures a single static frame.
- SVG
- Vector format, rasterized to pixels when loaded onto the canvas.
- BMP / ICO
- Uncompressed bitmap and icon formats, read directly by the browser.
Output Formats
- JPG
- Smallest files for photos. No transparency — a white background is added automatically.
- PNG
- Lossless with full transparency support. Larger file sizes than JPG or WEBP.
- WEBP
- Great balance of small size and quality, with transparency support.
- BMP
- Uncompressed, fully compatible bitmap — largest file size, no quality loss.

Convert Images Between JPG, PNG, WebP and BMP
This image converter can take supported source images such as PNG, JPG/JPEG, WebP, GIF, SVG, BMP and ICO and export the processed result as JPG, PNG, WebP or BMP. You can keep the original dimensions, enter a custom width and height, or use a preset size before exporting.
Use JPG when you want compact files for photographs, PNG when you need lossless output or transparency, WebP for efficient web delivery with transparency support, and BMP when you need an uncompressed bitmap format. GIF input is treated as a static image during canvas processing rather than preserving animation.
Resize, Fit or Crop an Image
The resize controls support three different workflows. Stretch forces the image to the exact target width and height. Fit keeps the entire image visible and adds padding when the target aspect ratio is different. Cover fills the complete output frame and crops the edges when necessary.
The live preview and crop overlay help you see the expected result before downloading the converted file.
How Browser Image Conversion Changes a File
This converter decodes the source image into pixels, draws those pixels to an HTML canvas, and then encodes the canvas into the selected output format. That means the exported file is a newly created image rather than a byte-for-byte copy of the original container.
EXIF, GPS and privacy
Many camera and phone images can contain metadata such as capture time, camera model, software information, orientation and—when location tagging is enabled—GPS coordinates. Because this tool renders pixels to a new canvas and exports a new file, those original metadata blocks are normally not copied into the result.
That behavior is useful for ordinary conversion, but it should not be confused with a formal metadata scrubber. Browser encoders, file formats and future browser behavior can differ. If you are removing sensitive location or identity information before publishing an image, verify the exported file with a dedicated metadata inspector rather than assuming the conversion alone is sufficient.
Orientation and rotated phone photos
Some JPEG photos store camera orientation separately from the pixel matrix. Modern browsers usually decode and display those files in their intended orientation, and this tool then rasterizes the displayed result into the new output. Because the conversion relies on browser decoding, unusual files or browser-specific handling can still produce different results. Always inspect the live preview before exporting.
Color profiles and appearance
Images may contain ICC or other color-profile information. Browser decoding and canvas rendering can convert colors into the browser's working color space, and the newly encoded output may not preserve the original embedded profile. For web graphics this is often acceptable, but photography, print and color-critical workflows should be checked in a color-managed editor after conversion.
Animation and multi-frame images
The current workflow processes one rendered frame through a standard canvas. Animated GIF input is therefore exported as a static image. The same limitation can apply to other multi-frame formats that a browser may decode visually. If animation must be preserved, use a dedicated animation-aware converter.
SVG rasterization
SVG input is vector-based, but this converter rasterizes it through the browser before export. The resulting JPG, PNG, WebP or BMP file is pixel-based and no longer contains editable vector paths. Choose sufficiently large target dimensions before exporting if the result will be displayed at high resolution.
Quality controls and file size
JPG and WebP expose a quality slider because their browser encoders support lossy compression controls. A higher percentage generally keeps more visual detail but usually produces a larger file. PNG is lossless in this tool and does not use the quality slider. BMP output is written as an uncompressed 24-bit bitmap, so files can be much larger.
Worked examples
Transparent logo to JPG: transparent pixels are filled with white because JPG has no alpha channel. Use PNG or WebP if transparency must remain.
Phone photo to 1080 × 1080: Fit keeps the whole image and adds padding; Cover fills the square and crops the edges; Stretch forces the dimensions and can distort the subject.
Animated GIF to WebP: the output from this tool is a single static frame, not an animated WebP.

Image Converter & Resizer FAQ
Does this tool upload my images to a server?
No. All image resizing, cropping, and formatting happens entirely within your web browser. Your files never leave your device, ensuring complete privacy and faster processing.
Why did my PNG's transparent background turn white?
If you convert an image with a transparent background to the JPG format, the transparent areas will automatically be filled with white because JPGs do not support transparency. To keep the background transparent, select PNG or WEBP as your output format.
What is the difference between 'Fit' and 'Cover' resize modes?
Fit (Pad) scales your entire image to fit inside the target dimensions, adding padding (transparent or white, depending on the format) to any extra space. Cover (Crop) scales your image up so it completely fills the target dimensions, cutting off the overlapping edges to guarantee a perfect fit without distortion.
Which output formats can I convert images to?
The current converter can export processed images as JPG, PNG, WEBP, or BMP. JPG and WEBP also support an adjustable quality setting in the tool.
Does the tool preserve animated GIFs?
No. GIF files can be opened as an input format, but the browser-based canvas workflow processes them as a single static image frame rather than preserving animation.
Can I resize an image to exact pixel dimensions?
Yes. You can enter a custom width and height from 1 to 8000 pixels, lock the aspect ratio, and choose Stretch, Fit, or Cover depending on how you want the image to fill the target size.
Are social media size presets included?
Yes. The tool includes preset dimensions for Instagram, Facebook, YouTube, and X / Twitter. Choosing a preset automatically fills the matching width and height values.
Does conversion remove EXIF or GPS metadata?
The tool creates a new image from canvas-rendered pixels, so original EXIF, GPS and similar source metadata is generally not carried into the exported file. However, this is not a dedicated metadata-sanitization guarantee; verify the output separately when privacy depends on metadata removal.
Can image colors change during conversion?
They can. Browser decoding, canvas rendering and output encoding may not preserve the source image's embedded color profile exactly, so color-critical work should be checked in a color-managed editor.
Does SVG stay vector after conversion?
No. SVG input is rasterized to pixels before export, so the resulting JPG, PNG, WebP or BMP file is no longer an editable vector graphic.
