How it works
How to use PixelVault
This tool is designed for practical image preparation before sharing, publishing or adding media to a website. It works without an account and creates a downloadable copy, leaving your original file unchanged.
1
Select images
Drop one or several images into the tool. The list stays in this browser tab.
2
Choose your output
Pick JPG, WebP or PNG, adjust quality, and optionally set a maximum width.
3
Download copies
Process the files and download each optimized image. Review it before replacing any original.
Useful, not decorative
A straightforward tool for everyday image work
↔
Resize with control
Set a maximum width while preserving the original aspect ratio. Useful for blog images and presentation slides.
⇄
Choose a format
Use JPG for photographs, WebP for efficient modern-web delivery, or PNG where transparent or lossless output matters.
Format notes
Choose output based on the job.
There is no single best image format. A photograph in a blog post may benefit from WebP or JPG, while a logo or diagram often needs PNG to preserve sharp edges and transparency.
JPG
Usually best for photographs. Reducing quality can substantially lower the file size, but excessive compression can create visible artifacts.
WebP
A modern format that often delivers smaller files at similar visual quality. Confirm that it suits your intended platform.
PNG
Useful for graphics and transparency. It is lossless here, so the quality slider does not affect PNG file size.
Answers
Frequently asked questions
Are my files uploaded or stored?
No. PixelVault uses JavaScript and the browser Canvas API to process selected images locally. There is no account, upload form, or server-side image storage in this version of the tool.
Will compression change my original file?
No. The tool creates a new downloadable image. Your original remains unchanged on your device.
Why does the result sometimes look different?
JPG and WebP are commonly lossy formats. Lower quality settings reduce size but may reduce fine detail. Use a higher quality value or PNG when preserving every pixel is more important than file size.
Can I use several images at once?
Yes. Choose or drop multiple supported image files. Each result receives its own download link.
Does PixelVault provide legal advice about images?
No. You remain responsible for your source images, permissions, licenses and how you use exported files.
