JPG, JPEG, PNG or WebP · up to 50MBMita Image Compressor is a free online image size reducer for JPG, JPEG, PNG and WebP files. You can reduce a photo for a website, application form, profile upload, email attachment or any platform with a file-size limit without installing extra software.
Select a JPG, JPEG, PNG or WebP image from your phone or computer, drag and drop it into the tool, or paste a copied screenshot. The image is opened directly in your browser so you can begin reducing its file size immediately.
Compress an image to 900KB, 500KB, 200KB, 1MB or enter a custom size in KB. You can also switch to quality mode for JPG and WebP when you prefer to control visual quality rather than target an exact file size.
The image compressor tests the required settings, reduces quality or dimensions when necessary, and shows the original and compressed sizes side by side. Compare the result, review any dimension changes, then download your lighter image.
Large images can slow down websites, take longer to send and fail on forms that impose maximum upload sizes. This image compression tool gives you a quick way to make an image smaller while keeping control of format, dimensions and quality.
Choose the popular 900KB preset when a profile page, school portal, job application, online form or website requires an image below roughly 1MB. The tool works toward the selected target automatically instead of making you guess a quality percentage.
JPG and JPEG photos usually respond very well to lossy compression. You can reduce photo file size substantially by adjusting encoding quality while keeping the original dimensions, or allow the tool to resize the image if a strict target requires it.
PNG is useful for graphics and transparent images but can be larger than JPG or WebP. The compressor can resize PNG images when necessary, and you can convert a PNG to WebP or JPG when a smaller file is more important than keeping the original PNG format.
Your image is processed locally by the browser rather than being sent through an upload queue. That means you can compress images online without creating an account, and the selected file does not need to be stored on Mita School's server.
An image compressor reduces the amount of data required to store an image. Depending on the format and the target you choose, that can involve re-encoding the image at a more efficient quality level, reducing oversized pixel dimensions, or converting the image to another format. The goal is a smaller image file that is easier to upload, share, store and serve on the web.
For example, a modern phone may produce a photo several megabytes in size even when the website receiving it only displays the photo at a much smaller resolution. Reducing that image from several MB to under 900KB or 500KB can make the upload faster without needing the full original data. For websites, smaller images can also reduce page weight and improve loading performance.
Best for photographs and images with many colours. JPG supports adjustable quality, so it is often the easiest format to compress to a specific size such as 900KB, 500KB or 200KB.
Best when you need transparency, sharp interface graphics or lossless storage. Because PNG is lossless, reducing dimensions or converting formats may be more effective than moving a quality slider.
WebP can provide strong compression while retaining good visual quality and can also support transparency. It is a useful output option when you want a smaller web image than a comparable JPG or PNG.
These answers cover the most common questions about reducing image size online, compressing photos to a specific KB limit and choosing between JPG, PNG and WebP.
Upload or paste your JPG, JPEG, PNG or WebP image, keep Target file size selected, choose 900 KB, and click Compress Image. The compressor automatically adjusts encoding quality and, when necessary, image dimensions to produce a lighter file as close as practical to 900KB. This is useful for profile photos, application forms, school or recruitment portals, websites and other services that reject images above a specified upload limit.
Mita Image Compressor supports JPG/JPEG, PNG and WebP input files. You can keep the original image format or choose JPG, PNG or WebP as the output. JPG is usually a practical choice for photographs, PNG is useful when transparency or lossless graphics matter, and WebP can provide a smaller web-friendly file while maintaining good visual quality.
No. The image compression process runs locally inside your browser using your own device. Your selected photo or image does not need to be uploaded to Mita School's server, there is no server-side upload queue, and you do not need to create an account before compressing or downloading the result. This browser-based approach also makes the tool useful when you simply want a quick private image size reducer.
Yes. In addition to the 900KB option, the tool includes presets for 200KB, 500KB and 1MB, plus a custom target field where you can enter another size in KB. The compressor works toward the maximum file size you choose. If quality adjustment alone cannot make the image small enough, it can progressively reduce the pixel dimensions to get closer to the requested target.
PNG is generally a lossless image format, which means a normal quality percentage does not reduce its file size in the same way it does for JPG or WebP. For that reason, the quality slider is disabled when PNG output is selected. If a PNG needs to become much smaller, the tool can reduce its dimensions, or you can convert it to WebP or JPG when transparency is not required. Converting can often produce a significantly lighter file.
It depends on the format and how aggressively the image is compressed. JPG and WebP can use lossy compression, which removes some image data to create a smaller file. At sensible settings, the visual difference can be minor while the file-size saving is substantial. The result area shows the original and compressed image sizes and lets you switch between previews before downloading, so you can judge whether the balance between image quality and file size works for you.
Yes. The image compressor is designed for modern mobile phones, tablets and desktop browsers. You can choose a photo from your phone and compress it without installing a separate app. Extremely high-resolution images can require a large amount of browser memory when decoded, so this version includes a safety check that automatically reduces unusually large processing dimensions rather than attempting an unsafe full-size canvas operation.
PNG and WebP can preserve transparent areas. JPG/JPEG does not support transparency, so if you convert a transparent PNG or WebP image to JPG, transparent pixels are filled with white. If your logo, graphic or product image needs a transparent background, keep PNG or use WebP rather than exporting it as JPG.
