Image Compressor
Compress JPG, PNG, WebP and AVIF images — by quality, or straight to a target size like 100 KB, 200 KB, 500 KB or 2 MB for forms and portals.
About Image Compressor
Large image files slow down websites, eat email attachment limits, and burn through storage quotas. This free image compressor reduces the file size of your PNG, JPEG, WebP, and AVIF images — often by 60–90% — while keeping them visually sharp. There is no sign-up, no watermark, and no software to install: pick a file, choose your quality, and download the result in seconds.
Compression works by re-encoding your image with a modern codec at a quality level you control. Converting to WebP or AVIF typically gives the biggest savings because both formats compress far more efficiently than legacy PNG or JPEG, and every modern browser supports them. That makes this tool ideal for web developers optimizing page speed, marketers preparing email banners, and anyone who needs a photo to fit under an upload limit.
If a form simply says "maximum 100 KB", "under 200 KB" or "not larger than 2 MB", switch to the target-size mode: type the limit (or tap a chip — 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, 2 MB) and the compressor lowers the quality step by step, and only if that is not enough shrinks the picture, until the JPEG or WebP fits. It tells you the final size and whether the limit was met, so a PRC, NBI, PhilHealth, Pag-IBIG, scholarship or job-portal upload that keeps rejecting your photo goes through first time.
How to compress an image online
- 1Drag and drop your image into the upload zone, or click it to browse for a file on your device.
- 2Choose an output format — WebP or AVIF for maximum savings, or keep JPEG/PNG if you need those exact formats.
- 3Adjust the quality slider. 70–85% is usually indistinguishable from the original at a fraction of the size.
- 4Click Compress and compare the before/after file sizes shown on screen.
- 5Click Download to save the compressed image to your device.
Frequently asked questions
How do I compress an image to under 100 KB, 200 KB or 2 MB?
Upload the image, choose "To a target size", type the limit in KB (1 MB = 1024 KB, 2 MB = 2048 KB) or tap one of the chips, keep JPEG if the portal wants JPG, and click Compress. The tool steps the quality down until the file fits and shows you the result; it only shrinks the pixel size if quality alone cannot reach the target.
Does compressing an image reduce its quality?
Lossy compression removes detail your eye is unlikely to notice. At 75–85% quality, most photos look identical to the original while shrinking dramatically in file size. If you need pixel-perfect output, use PNG, which is lossless.
Which format gives the smallest file size?
AVIF usually produces the smallest files, followed closely by WebP. Both routinely cut file size by more than half compared to an equivalent-quality JPEG, and both are supported by all modern browsers.
Is there a file size limit?
Yes — images up to 50 MB are supported, which comfortably covers photos from any modern phone or DSLR camera.
Are my images stored on your servers?
No. Images are processed in memory or in short-lived temporary files that are deleted as soon as your compressed image is delivered. Nothing is kept, logged, or shared.
Is this image compressor really free?
Yes — completely free, with no sign-up, no watermarks, and no daily limits beyond fair-use rate limiting.
