Tool 3.2

Image compressor (JPEG, PNG, WebP)

Shrink JPEG, PNG and WebP images by quality, dimensions or a maximum size in KB, several at once. Compressed in your browser; the images aren't uploaded.

Runs on your deviceRuns entirely in your browser: nothing you type or upload leaves your device.

How to use it

Drop one or more images, or click to choose them.
Adjust the quality slider, and optionally a max width or height or a different format.
Compare the before and after sizes and download each compressed image.

Why a phone photo is too heavy for an upload form

A photo from a recent phone is several megabytes and often 12 megapixels or more. That is far more than a form needs. Job portals, university applications, insurance claims and many government procedures limit each file to 100 KB, 200 KB or 1 MB, and simply reject anything bigger.

Most of that weight is detail nobody will see. A photo of your ID, a receipt or a certificate stays readable at 1600 pixels wide, and a quality around 70 removes what the eye doesn't notice. This tool does both, and with Max size (KB) it lowers the quality, then the dimensions, until the file fits the limit.

Example: a diploma photo for a 200 KB limit

You photograph a diploma with your phone: diploma.jpg, 4032×3024 pixels, 3.1 MB. The form says "maximum 200 KB, JPG". Set Max width to 1600 and Max size (KB) to 200, and leave Format on Auto.

The result row reads something like 4032×3024 → 1600×1200 · 3.1 MB → 188 KB (−94%): first the dimensions before and after, then the weight before and after. The new file is called diploma-compressed.jpg. Before you upload it, open it and zoom in on the smallest text. If you can read it, the form's reviewer can too.

What compression can't fix

It can't make a blurry or dark photo sharper, so take the picture in good light, straight on, filling the frame with the document. Always compress from the original: compressing an already compressed JPG again and again adds blotches each time.

The compressed copy doesn't keep the photo's hidden data (EXIF), such as the GPS location and the camera model, and photos taken sideways are turned upright first. Very large images are reduced to 16 megapixels, the most some phones' browsers can process. If a row says the result is larger than the original, keep the original file.

FAQ

How do I compress a screenshot?

Copy it and press Ctrl+V on this page: the drop area also takes pasted images. Screenshots are usually PNG; with Format on Auto they are saved as JPEG, or as WebP if they have transparent areas, which is much smaller. For screenshots full of text, keep the quality around 80 so the letters stay sharp.

What quality should I use?

For photos, 70–80 usually looks the same as the original at a fraction of the size. Go lower for thumbnails, higher for images you plan to print.

Why did my PNG get bigger?

When the output stays PNG (Format set to PNG, or Same as original), the quality slider does not apply, because PNG is lossless. Leave Format on Auto, choose JPEG or WebP, or reduce the dimensions.

How do I get an image under 100 KB (or any size limit)?

Type the limit in Max size (KB), for example 100. The tool lowers the quality step by step and, only if that is not enough, the dimensions, until the file fits. Auto saves photos as JPEG, which forms and government portals accept, but images with transparency, like a logo, as WebP. If the form only accepts JPG, choose JPEG in Format: transparent areas become white.

JPEG, WebP or PNG: which format should I pick?

JPEG for photos and for any form, because every site and program opens it. WebP gives a smaller file at the same quality and keeps transparency, but some forms and older programs don't accept it. Keep PNG only for screenshots or logos where every pixel must stay exact, knowing it won't get much smaller here.
