Search results for “free resizer” are full of watermarked downloads and installer upsells. This spoke is the no-account Canvas path: eligible everyday jobs, no Convertify4u stamp, no upload on the Instant path. Pro exists on the site for other heavy products (OCR, dedicated infrastructure) — changing width and height in the tab is not that.
You still need a modern browser and enough RAM. A 100 MB panorama can kill a phone tab; that is physics, not a fake free tier. HEIC may need a convert. Exact social boxes, print DPI, and PNG alpha have their own spokes — this page is the friction briefing.
Keep the original until you like the preview. Free and local is not an excuse to overwrite the only copy of a trip still with a stretched 640px JPEG.

What “free in the tab” means for pixel changes
No email form, no stamp
Open, drop, type, download. Comparison clouds may be faster on a farm; they hold the still. We hold your CPU. If a site requires Google login to get the file, it was never free in this sense.
Limits that are honest
10,000 px cap. Upscaling does not restore detail. Sequential bulk, not a 500-file ZIP. JPEG/PNG/WebP/GIF inputs. Those are product facts, not a surprise paywall at download.
When to leave this spoke
Need 1080×1920 explained? Social spoke. Need 300 DPI math? Print spoke. Need 100KB? Reduce-size. Need holes preserved? PNG spoke. This URL is for people who already know the integers and refuse an account wall.
How it works
- 1
Stay in the browser you already have
Chrome, Edge, Safari, Firefox. No installer. No newsletter.
- 2
Drop the still and type width and height
Lock aspect unless you mean to stretch. Preview at a real zoom.
- 3
Download and keep the original elsewhere
Close the tab; the working bitmap is gone. Your downloads folder is yours.
Use cases
One still before a form closes
No account creation in the last five minutes of a deadline.
School or work PCs that block installs
A tab is allowed. Photoshop is not.
People who refuse random GPU uploads
Canvas stays here. That is the product.
Problems we solve
Watermarked “free” downloads
A stamp makes the still unusable in an ad. Ours has none.
Installer upsells
If a site offers a .exe, leave. This is HTML and Canvas.
Login walls at download
Everyday Instant geometry does not require Google.
Trust & technology
No account wall
Eligible everyday jobs skip the newsletter.
Local Canvas
No Convertify4u copy of the still.
No watermark
The file is yours.
