ImpressaPic is a versatile image tool that lets you: convert images between JPEG, PNG, and WebP formats; add customizable text watermarks with different fonts, sizes, colors, and positions; apply image watermarks with adjustable size, position, opacity, and rotation; process multiple images at once; compress images with adjustable quality; and all of this works offline once you've loaded the site. The best part is that everything happens right in your browser - no uploads needed!

Yes, ImpressaPic is completely free to use. There are no hidden fees, subscriptions, or premium features. All functionality is available to everyone without any limitations. The only restriction is the file size limit, which is due to browser capabilities, not a premium feature.

We support JPEG, PNG, and WebP formats. You can convert between any of these formats.

Yes, each file can be up to 50MB, and you can convert up to 20 files at once with a total size limit of 200MB. This is the only limitation in the app, and it exists due to browser memory constraints, as all processing happens locally in your browser. However, there's no limit on the number of operations you can perform - if you need to convert more than 20 files, you can do it in multiple batches, and your settings (watermark, quality, etc.) will be preserved between uploads.

Yes! All processing happens directly in your browser. Your images are never uploaded to any server.

You can add both text and image watermarks. For text watermarks, you can customize the font, size, color, position, and opacity. For image watermarks, you can adjust size, position, opacity, and rotation.
