Supported image formats
Upload JPG, JPEG, PNG, and WebP. For the result, you can keep the original format or choose JPG, PNG, or WebP.
PNG
Best for logos, screenshots, and graphics with transparency. PNG uses lossless pixel compression, so the result is not always smaller than the source.
WebP
A modern format for websites and everyday use. It usually produces compact files, supports transparency, and helps preserve visual quality.
If transparency is not needed, converting PNG to WebP or JPG often reduces the file more. To get closer to a target size, lower quality and image resolution.
Frequently asked questions
Are files uploaded to a server?
No. Preview, compression, and resizing run locally in your browser — images are not sent to Packlet servers.
Can I compress several images at once?
Yes. Add several images or photos, process them in one queue, then download them individually or as one ZIP archive.
Which formats are supported?
You can add JPG, JPEG, PNG, and WebP. The result can keep the original format or be saved as JPG, PNG, or WebP.
Can I resize an image?
Yes. Set a maximum width, height, or both dimensions in pixels. If needed, the tool preserves aspect ratio and avoids upscaling small images.
Should I choose JPG, PNG, or WebP?
JPG is usually best for photos without transparency, PNG for transparent graphics, and WebP when you need a compact modern format for websites or sharing.
Why did a PNG become larger after compression?
PNG uses lossless compression and size depends on image content. Try reducing resolution or choose WebP or JPG if transparency is not required.
Is GIF supported?
No. GIF is not supported in the current version. Add an image in JPG, PNG, or WebP format.
Will image quality be reduced?
Lowering JPG and WebP quality removes some data. Choose high quality for compression without obvious visual changes and check the result in preview.
