Hitting an upload limit without wrecking the picture

Upload caps are byte limits, and this tool works the byte side: same dimensions, stronger compression. Step the quality down until you pass the cap; if quality has to fall uncomfortably far, shrinking the dimensions a little is the better-looking route to the same number.

Fact	Detail
Dimensions	Unchanged
Typical form caps	1–2 MB
Fresh phone photo	Often 4–12 MB — routinely over cap
Screen use after reduction	Nearly always fine
Print use	Be conservative — artefacts show in print

Typical jobs people use this for

Getting a passport-style photo under a visa portal's 1 MB limit
Fitting a job application's document-size ceiling
Shrinking listing photos for a marketplace with strict caps

When this is the wrong tool

If the image is also far larger in pixels than it will ever display, resize first — you'll hit the cap with quality to spare. For images headed to print, reduce gently; compression that's invisible on screen appears on paper.

Frequently Asked Questions

What is the difference between reducing size and resizing?

Reducing file size lowers the number of bytes while keeping the same dimensions, by compressing more aggressively. Resizing changes the pixel dimensions themselves. If your image is the right size on screen but too heavy to upload, this is the tool you want.

How do I hit a specific size limit?

Adjust the quality setting and check the resulting file size, lowering it in steps until you are under the limit. If quality has to drop uncomfortably far, reducing the dimensions as well is usually a better-looking route to the same target.

Why do upload forms reject my photos?

Phone cameras produce files of several megabytes, while many forms — job applications, government portals, older systems — cap uploads at 1–2 MB. Modern phone photos routinely exceed those limits straight out of the camera.

Will the image still look acceptable?

For on-screen use, almost always. Compression artefacts become visible when you zoom in or print, so if the image is destined for print rather than a web form, be more conservative with how far you push it.

Does the file get uploaded?

No. Everything is processed locally in your browser.
