Resize & compress images.
Exact pixels or a percentage — plus real compression: drop the quality, convert to WebP and watch the file size fall live. Batch friendly, nothing uploads, no watermark.
PNG, JPG or WebP · one or many · resizes locally, nothing is uploaded
How it works
Drop your images
PNG, JPG or WebP — one file or a whole batch. They load instantly because nothing uploads.
Set the size
Type exact pixels with the aspect ratio locked, or enter a percentage to scale proportionally. Or switch to canvas mode: the image sits scaled inside your exact dimensions, over a background color or full transparency.
Download
One image downloads directly; a batch arrives as a single ZIP — every file resized with the same settings, no watermark.
Why use this tool
Oversized images are the quietest performance killer on the web: a 4000-pixel photo squeezed into a 400-pixel slot still ships all sixteen-million pixels to every visitor. Resizing to the display size — and converting to WebP while you're at it — is routinely the single biggest page-weight win available, and it takes seconds here. The same controls double as an image compressor: keep the dimensions, lower the quality or switch the format, and the live readout shows the compressed size before you download — no guess-and-check loops. The same applies to email attachments, marketplace listings, CMS uploads with size limits, and anywhere else a "file too large" message has ever annoyed you.
For logo work specifically, this pairs with the rest of the toolbox: make the background transparent first, resize here, or skip fixed sizes entirely by converting the logo to SVG so it scales forever. Need every social platform's exact dimensions in one go? The social media resizer does all of them at once — this tool is for when you choose the numbers.
Frequently asked questions
Does resizing reduce image quality?
Downscaling uses high-quality stepped resampling, so smaller versions stay sharp. Upscaling cannot invent detail — a small image enlarged a lot will soften; for logos, a vector SVG is the better route.
Can I resize multiple images at once?
Yes — drop in several files, set one size or percentage, and download them all as a single ZIP. Each image keeps its own aspect ratio when the lock is on.
What formats are supported?
In: PNG, JPG, WebP and any image your browser can decode. Out: keep the original format, or convert to PNG, JPG or WebP with a quality slider for the lossy formats.
How do I compress an image without changing its dimensions?
Leave the size unchanged, then lower the quality slider or convert to WebP — the readout next to the slider shows the exact new file size live. Converting a PNG to WebP alone often cuts the file size dramatically.
Are my images uploaded to a server?
No. Reading, resizing and encoding all happen inside your browser tab — nothing is transmitted, which is why it is instant and private.
What happens to transparency?
PNG and WebP outputs keep transparent backgrounds. JPG does not support transparency, so transparent areas are filled with white — the tool warns you in the preview.
