You have picked a photo, filled in the form, and reached the upload button—then the file is too large. Choose the maximum size the form allows, such as 50 KB or 100 KB, and make a smaller copy here.

The reducer adjusts JPEG quality first. If the photo still does not fit, it makes the dimensions smaller too. A plain portrait usually needs less space than a detailed scene, so two photos with the same dimensions can finish at different sizes.

Check the result before downloading. Faces should still be recognisable, and any writing should be easy to read. If you only need to change the dimensions or file format, use one of the separate tools below instead.

Before you save the result

For text or identity documents, zoom in after compression. A smaller file is not useful if the information is unreadable.

Transparency is flattened to white for JPEG output. Use a PNG conversion or the background remover when a transparent result matters.

Choose the change your image actually needs

Start with the rejection message

“File too large” usually points to KB or MB. “Invalid dimensions” points to pixels. “Unsupported format” means the website cannot use that file type. Read the exact message before editing; compressing again will not fix the wrong shape or an unsupported extension.

Use the clearest version you have

A screenshot of a photo often includes extra borders, interface text or a different crop. If the original camera photo is available, use that instead. Keep it separately and make copies for each destination, rather than repeatedly editing the latest compressed version.

Make changes in a useful order

For a form with several requirements, crop unnecessary space first, set the requested dimensions next, and compress only if the file is still too large. Check the accepted format before starting. This order makes it easier to tell which change solved the problem.

Give the download one final check

Open the saved copy, not just the preview. Look at the face, signature or product detail that matters, then compare its dimensions and size with the destination’s instructions. A smaller file is only useful if it still contains the information you need.

Examples to help you choose
What the destination asks for	Start here
A file below a KB limit	KB reducer or Custom Image Size Reducer
A particular width and height	Crop Image, then Image Resizer
JPG instead of HEIC or WebP	The matching format converter
An image without its background	AI Background Remover

EXAMPLE 01

Keep fine detail

An 85% JPEG quality example keeps a generous detail budget. Compare hair, leaves and fine edges before using the export.

EXAMPLE 02

Make everyday images lighter

A 65% quality example can suit images displayed at smaller sizes. The measured file sizes show whether the export actually saves space.

EXAMPLE 03

Explore the size–quality trade-off

A 40% example makes compression more aggressive. Look for blocky textures or rough edges and choose a higher quality when needed.

Frequently asked questions

Do I need an account?

No. Choose your image, process it and download the result. There is no signup step or watermark.

Does my photo leave my device?

The photo is processed in this browser. The HEIC and AI tools may download extra files to do their work, but they do not upload your photo to a processing service.

What if the form asks for both pixels and KB?

Check both requirements. Resize or crop the image to the right dimensions first, then use the KB reducer if it is still too large.

Can I get the original back?

The original file on your device is not changed. Keep it so you can make another copy if the first result loses too much detail.

Should I rename a .webp file to .jpg?

Renaming only changes the filename. Use a format converter to create a real JPEG file that another app can read.

Will a new copy keep camera metadata?

The browser exports do not deliberately copy camera or location metadata. Keep the original file if that information matters for another workflow.
