Image compressor
Compress images to 1 MB
Camera photos are big; upload caps are not. 1 MB is preselected below — adjust freely. Everything runs on your device, every result is measured from the real output file, and quality trade-offs are documented on the card, never hidden.

Resize pixels (optional)
Aspect ratio is always preserved. Leave blank to keep the original pixels.

What 1 MB means for quality
At 1 MB the encoder is generous: most files meet the cap through quality tuning alone with dimensions untouched. The result card shows the measured before → after and the levers used, plus a before/after slider so you can judge rather than trust. If an image is already optimised, you get a clear no gain state instead of a pointless re-encode.
Transparent PNGs keep their alpha: WebP alternatives that preserve transparency are offered when the browser can encode them, and flattening only happens if you click the option explicitly labelled as flattening.
1 MB questions, answered honestly
When is 1 MB the right target?
When quality still matters: portfolio uploads, marketplace photos, documentation pictures that someone may zoom into, and any upload cap around the 1 MB mark that rejects 5–10 MB camera originals.
How much does 1 MB shrink a camera photo?
A modern phone photo (typically 3–10 MB as JPEG, more as PNG) lands at 1 MB with modest, mostly invisible changes at screen sizes — high quality retained after re-encoding, and downscaling reserved for when the numbers demand it.
Can I resize dimensions too?
Yes — open the dimension limiter to cap width and height in pixels. It combines with any KB target. If a portal needs, say, exactly 1600 px wide, set that here and let the engine handle compression.
What files can be processed, and how many at once?
JPG, PNG and WebP inputs as they come out of your camera or exports. Up to 24 files per batch, processed sequentially with a ZIP of all results at the end. Each file tells its own honest story — some meet the cap outright, some need a resize.
Do I even need to compress a photo to 1 MB?
Only if a portal asks for it. Phone photos are usually 3–10 MB, so a 1 MB copy keeps quality high while satisfying a common upload ceiling — and if no ceiling applies, the original is already fine.
Will compressing to 1 MB reduce my image dimensions?
Almost never. At 1 MB the quality pass alone is normally enough, so the pixel size stays exactly as it was and you keep a full-size image that is simply lighter.
