The compressor will try to stay below this size when possible; it is not an exact guarantee.
Resizing preserves aspect ratio and never enlarges smaller images.
Settings are locked until the current batch finishes or is cleared.

Choose JPG, PNG or WebP files to begin.
A SIMPLE WORKFLOW
Smaller images in four clear steps
Choose the balance that works for your images, then keep each result or download the completed batch.
Adjust Your Settings
Set an approximate target, maximum dimensions, output quality and format without technical guesswork.
Process Locally
Browser JavaScript reads and optimizes the image content on your device instead of sending it to our servers.
Download the Results
Compare sizes and dimensions, download files individually, or create a ZIP after processing finishes.
LOCAL PROCESSING
Your image takes a shorter, private path
Your image content is processed locally in your browser and is not uploaded to ImagesCompressor servers. The page also requests its compression and ZIP libraries from a CDN and loads a separate third-party advertisement. Those requests may process technical browser or device data, but the tool does not intentionally provide selected image content to the advertising script.

SUPPORTED FORMATS
Choose the right output for the job
Conversion can remove metadata and may increase size when the source is already efficient, so compare the finished result.
JPEG / JPG
Best suited to photographs and images with many colors. JPEG is generally lossy and does not support transparency.
Compress JPG imagesPNG
Useful for graphics, screenshots and transparency. Canvas PNG export does not use the quality slider like JPEG or WebP.
Compress PNG imagesWebP
A modern web format that supports lossy output and transparency. Export availability depends on the browser.

Image compression FAQ
Direct answers about privacy, quality, formats and browser limits.
Are my images uploaded to a server?
No. Your image content is processed locally in your browser and is not uploaded to ImagesCompressor servers. Third-party scripts may make separate network requests but do not need access to your images.
Is ImagesCompressor free?
Yes. The tool is free to use, with no account or payment required.
Which image formats are supported?
JPG, PNG and WebP are supported. WebP export depends on browser support.
Can I compress multiple images at once?
Yes. You can queue up to 50 images, with a limit of 25 MB per file.
Does image compression reduce quality?
It can. Lossy JPEG and WebP compression trades some image detail for a smaller file, while the visible difference depends on the chosen settings.
What is the difference between JPEG, PNG and WebP?
JPEG is efficient for photos, PNG supports lossless graphics and transparency, and WebP often provides smaller web files with optional transparency.
Are EXIF metadata preserved?
Not by default. You can enable EXIF preservation, but metadata may include private information such as location.
Can I use the image compressor on mobile?
Yes. Modern mobile browsers can process images, although large files may be limited by device memory.
How can I reduce an image to approximately 100 KB?
Set the target maximum size to 0.1 MB. The compressor will try to reach it, but an exact result cannot be guaranteed for every image.
Why did my converted image become larger?
Conversion does not always reduce size. The source content, output format, dimensions and prior optimization all affect the result.
Can transparent PNG images be converted to JPEG?
Yes, but JPEG does not support transparency, so transparent areas are filled with white.
Do I need to create an account?
No. You can use the tool immediately without registering.
