Compress images
Make image files smaller while keeping them looking good. Process one image or a whole batch.
Free, private image processing
No signup is required. Images are processed locally and are never uploaded. JPG, PNG, WebP, HEIC and AVIF still images are supported, including batches of up to 50 files.
Are my images uploaded?
No. Processing happens locally in your browser. PlainImage never receives your images, filenames or embedded location data.
What does compression change?
For photos, lower quality removes fine detail to make a smaller file. Preview the result against the original before downloading. PNG compression remains lossless.
Is it free?
Yes. There is no account, watermark, daily allowance or paid download step.
