Free Online Image Compressor, Converter and Resizer
Photo KB Tools offers free online image tools to compress photos, reduce image file size, convert JPG and PNG images, and resize pictures to custom dimensions. Whether you need to make a photo smaller for an online form, prepare images for a website, or adjust picture dimensions for sharing, choose the tool that fits your needs.
Use the image compressor to work toward a target file size, convert images between supported formats, or resize pictures in pixels. Process your images in your browser and download the result when it is ready.
Compress Images to 50KB, 100KB or 200KB
Need to reduce an image to a specific KB size? The image compressor lets you enter a target such as 50KB, 100KB, 200KB, or another supported value. This can be useful when uploading photos to websites, online applications, forms, and services with image size limits.
To compress an image, select a supported JPG, PNG, or WebP file, enter your target size in KB, choose an output format, and click Compress Image. Review the resulting file size before downloading.
The final size depends on the image dimensions, image content, output format, and compression settings. An exact target cannot be guaranteed for every image. PNG compression in this tool does not use the same quality adjustment method as JPG or WebP, so the resulting PNG may remain larger than your target.
PNG to JPG Converter Online
Use the PNG to JPG converter when you need a JPG version of a PNG image. JPG is commonly used for photographs, website images, and everyday picture sharing. You can adjust the JPG quality setting to balance file size and visual appearance.
JPG does not support transparency. If your PNG contains transparent areas, they are filled with white during conversion. Always check the converted image to make sure it looks right for your intended use.
JPG to PNG Converter
Convert a JPG image to PNG when a website, application, or workflow requires the PNG format. Select your JPG file, start the conversion, and download the resulting PNG image when it is ready.
Changing JPG to PNG does not restore image details lost during the original JPG compression. The PNG file may also be larger than the source image. Choose the format according to your quality, compatibility, and file size requirements.
Resize Images Online to Custom Dimensions
The online image resizer helps you change the width and height of a picture in pixels. Resizing can be useful for profile photos, website graphics, online forms, document images, and social media content.
Select a JPG, PNG, or WebP image, enter the desired width and height, and choose whether to keep the original aspect ratio. Select an output format and click Resize Image to create your resized picture.
Keeping the aspect ratio helps prevent unwanted stretching. Resizing changes the image dimensions but cannot recreate details that were missing from a low-resolution original.

Image Privacy and Browser-Based Processing
The image-processing functions in this tool use your browser to read and process the selected image with browser image and canvas features. The image-processing code shown on this page does not intentionally upload the selected image file to a remote server.
Image processing may use your device's memory, particularly with large pictures. Website hosting, analytics, advertising, or other third-party scripts may have separate data practices, so review the relevant privacy information when deciding which files to process.
Frequently Asked Questions
How can I compress an image to 50KB?
Open the Exact KB tool, select a supported image, enter 50 in the target size field, and click Compress Image. Check the resulting file size. If it remains above your target, try reducing the image dimensions or choosing another output format.
Can I reduce a photo to 100KB online?
Yes. Enter 100KB as the target in the image compressor. The tool will try available compression quality settings for JPG or WebP. The final result depends on the image, and an exact file size is not guaranteed.
How do I convert PNG to JPG?
Select the PNG to JPG tab, upload your PNG image, choose the JPG quality, and click Convert PNG to JPG. The converted image can then be downloaded after the countdown.
Does converting JPG to PNG improve image quality?
No. Format conversion does not recover details already lost from the original JPG. PNG may also create a larger file than JPG.
Can I resize a photo to a specific width and height?
Yes. Select Resize Image, upload a supported image, and enter the required width and height in pixels. Keep aspect ratio enabled if you want to preserve the image's original proportions.
Which image format should I use for smaller files?
JPG and WebP can be useful for reducing photograph file sizes, depending on the image and selected quality. PNG may be more suitable for graphics or workflows that require PNG. Compare the resulting file size and visual quality before choosing.
Can I use these image tools on a mobile phone?
The page is designed to work with supported mobile and desktop browsers. Processing speed depends on your device, browser, image dimensions, and file size.
Are my selected images uploaded to a server?
The image-processing code on this page processes selected images in the browser and does not intentionally send the image files to a remote server. Other website components may have separate data practices.
