Compress image to 1MB
Bring oversized images under 1MB without uploading them or giving up more quality than the limit requires.
Exact-size compressor
Files stay on this device
Advanced settingsResize, crop, quality
Dimensions never upscale. JPEG fills transparent pixels with white. GIF and animated WebP inputs become a static first frame.
Ready when you are. No image data is sent over the network.
On-device processing
No image upload endpoint exists.
Measured output
Success uses the real output bytes.
Batch ready
Process 20 files and download a ZIP.
Pick the limit your form asks for
Every page uses the same private compressor with the target already selected. You can still enter a custom value at any time.
High quality with a predictable ceiling
A 1MB target is generous enough for detailed screen images while still avoiding oversized uploads and slow transfers.
Where this target helps
High-resolution profile and portfolio images
Website assets that need a firm size ceiling
Email attachments and shared photo collections
Highest useful quality, without guesswork
Search quality first
JPEG and WebP outputs use a binary search to find the highest encoder quality that stays below 1MB.
Resize only when required
If quality alone cannot reach the limit, the engine reduces dimensions and searches again. It never upscales the source.
Show the honest result
Every download reports its measured bytes, dimensions, savings, and whether the requested maximum was reached.
Choose the right format
- JPEG
- Broadly accepted and efficient for photographs. Transparency becomes white.
- WebP
- Often smaller at similar quality and can preserve transparency.
- PNG
- Lossless and good for sharp graphics, but harder to fit under tiny limits.
Questions before you compress
Is 1MB treated as 1000KB or 1024KB?
This tool uses 1024KB for the 1MB preset and reports the exact byte size of every result.
Why is the result much smaller than 1MB?
The target is a maximum, not a request to inflate the file. The compressor never adds waste just to approach the limit.
Can I download a full batch together?
Yes. After processing, Download all creates a ZIP file locally in your browser.
Your images stay yours
The compressor has no image upload API. Analytics, when allowed, records only page and tool events without file names or contents.
