What this image compressor fixes

Most “free” image compressors limit you to a handful of files, cap the file size, or upload everything to a server. This PlainBench tool skips all of that.

No size or count limits* on images – add as many large photos as your device can handle.
Batch compression with one click, or compress and download individually.
Quality slider + presets so you can choose between “tiny file” and “near-original.”
Optional resize for max width/height to keep blog and social images consistent.
Target size per image (in KB/MB) so you don’t have to guess for uploads and forms.
Client-side only. Images never leave your browser, so no tracking or surprise storage.

*Real-world limits are whatever your browser and device can handle comfortably (e.g., thousands of megapixels may just be slow).

Does this upload my images anywhere?

No. Everything happens locally in your browser using the canvas API. Once you close the tab, the images are gone. This is useful for sensitive photos or client work.

How much can I shrink my images?

It depends on the image and settings. Photos from phones and cameras often shrink by 60–80% with a balanced quality setting – especially if you resize to realistic web dimensions.

Will compressing hurt image quality?

Lossy compression always trades some detail for smaller file size. The default “Balanced” preset aims to keep images looking good for normal viewing. If quality is critical, choose “Keep quality (light)” and avoid very low quality values.

Is this good for SEO and page speed?

Yes. Smaller images mean faster pages, lower bounce rates, and better Core Web Vitals – all of which help search performance. This tool makes it easy to batch optimize images before you upload them to your site or store.
