Upload an image, choose a compression preset or custom quality, preview the size change and visual result, then download the compressed file. Useful for website images, product photos, blog graphics, article covers, and files that are too large to upload.
Check the preview and file-size change first, then decide whether to download. That is more reliable than judging by preset names alone.

Compress JPG, PNG, and WebP images online. Upload an image, choose a compression preset or adjust quality with the slider, preview size reduction and visual result in real time, then download the compressed file. Everything runs locally in your browser.
Image compression is not about making every file as small as possible. The real goal is balancing file size with usable clarity. The page shows original size, compressed size, and reduction percentage so you can judge the setting quickly.
Routine images can use preset compression levels. If you need to meet a strict upload limit, preserve text edges, or control output size more carefully, use the custom quality slider.
Many images that need compression are not ideal for remote upload first, such as admin screenshots, client visuals, product images, unpublished article graphics, or internal marketing assets. This page keeps compression and export inside the browser.
Image compression is usually done before publishing or upload. After reducing file size, check whether the visual quality, dimensions, and target platform rules still work.
Website visuals, article graphics, and blog covers often do not need the full original file size. Compressing them before upload helps reduce page weight and makes content publishing easier.
Many CMS forms, store backends, editorial tools, and submission systems impose image size limits. Compressing the file before upload helps reduce upload errors and rework.
Photo-based images often compress best as JPG or WebP. Images with transparency, interface edges, icons, or text overlays are often safer as PNG. Picking the right format usually leads to a better compression result.
Common questions about online image compression, reducing image size, compression quality, and upload limits.
Usually there is a tradeoff between file size and image quality. Stronger compression makes the file smaller, but it can remove more detail. The safer approach is to compare the size change first, then check whether the image still meets the actual display need.
Photos are usually better candidates for JPG or WebP because those formats often compress more aggressively. PNG is safer for transparent backgrounds, interface graphics, text overlays, and sharper edges. The best choice depends on both image content and the upload rules of the target platform.
Usually the file itself has not changed. The page shows the size of the browser-generated output and formats it for readability, while your operating system may use a different unit conversion or rounding method. A difference of 1 KB to a few KB is normal. The downloaded file is the same one used for the current preview.
You can adjust it yourself. This page keeps the common presets for speed and also adds a custom quality slider. Presets are faster for routine work, while custom quality is more useful when you need to meet stricter upload limits or preserve more text and edge detail.
Start with the balanced preset and check the size change. If the file is still above the upload limit, switch to stronger compression or use the custom quality slider. This page uses local browser compression, so keeping each image within 30 MB leads to more stable results.
No. Compression and export run locally in the browser, and the source image is not sent to a server. That is more practical for admin screenshots, client assets, product photos, and unpublished graphics.
