TOOL-SPECIFIC GUIDE

How to use Compress Image

1. Select your input

Choose a JPG, PNG or WebP image from your device using the file button or supported drop area. The standard file picker accepts browser-readable images up to 25 MB; decoding support depends on the file and browser.

2. Understand the settings

Light starts at 90% quality, Balanced 82%, Strong 65% and Maximum 45%. The quality slider refines that choice. Keep, JPG, PNG or WebP controls the encoding.

3. Process and review

Choose Balanced, click Process image, compare the original and result size, and raise quality if text or fine edges look rough.

4. Save your result

Use the result’s Download control after processing. Keep your original separately and inspect the exported copy at its intended display size; the preview alone is not the file you will share.

Supported formats

Input: browser-readable images, normally JPG, PNG and WebP, up to 25 MB. Output controls include the shown Keep, JPG, PNG or WebP choices. Keep preserves a supported source encoding choice, not byte-for-byte original data; animation is not preserved.

When to use this tool

Shrink one photo for email or a web page with quality and format controls. Start with Balanced and compare the exported file size.

What to check in the result

Small lettering, skin texture and gradients are useful comparison areas. PNG may remain large because its browser encoding does not use JPG-style lossy quality control.

Continue with Resize Image when that step fits your workflow.

A practical example

A holiday photo can be exported as a smaller JPG for email; compare the downloaded result at normal viewing size.

Capabilities and limitations

Lossy JPG/WebP output can change pixels. PNG encoding may remain large. The tool does not guarantee a requested KB size.

Troubleshooting

PNG is still large? PNG quality is not a lossy compression control; try JPG for an opaque photo or WebP where the receiving app supports it. If edges look rough, increase quality.

Processing and privacy

Image pixels are processed on your device. Loading the website and processing assets still uses a network connection, and hosting may receive normal request information. Keep original files backed up.

Questions about Compress Image

Why does the PNG stay large?

PNG encoding does not use the JPG-style quality reduction in the same way. Photographs often become smaller as JPG or WebP, while PNG is useful for transparency.

Can I choose an exact KB target?

No. Compare the output size and adjust format or quality; this version does not guarantee an exact byte target.
