01Why this resizer
Resize photos in seconds, not minutes.
Four reasons designers, shop owners, and photographers keep this page bookmarked over the desktop tools they used to open.
- 01
Exact pixels or smart percentages
Type the dimensions you need in pixels, or scale the image down to 25, 50, 75 percent — whichever matches how you think.
- 02
Locked aspect ratio by default
The ratio stays in sync as you type so portraits never get squished into squares. Unlock it any time for a free resize.
- 03
Instant, in-browser resizing
No upload queue, no progress bar — the image is resized the moment you click Resize, even at 50 MB original sizes.
- 04
Stays on your device
Everything happens locally with the Canvas API. Your photos never travel to a server, which keeps personal pictures personal.

03Use cases
Where people resize first.
Whatever pixel target you are aiming for, the workflow is the same: drop, set, download. Here are the cases that come up most.
Product photos for stores
Shopify, Etsy, and Amazon each want specific pixel sizes. Resize once and ship listings that load fast and look sharp.
4000 × 3000 → 1500 × 1125Hero banners & web headers
Trim a massive DSLR shot down to the exact width your site needs so users do not download megabytes they will never see.
5760 × 3840 → 1920 × 1280Social media posts
Snap a portrait or feed image to the exact dimensions Instagram, X, or LinkedIn expects — no cropping surprises later.
4096 × 4096 → 1080 × 1080Avatars & profile pictures
Shrink a high-res selfie to a tidy 400 × 400 PNG so profiles load instantly and stay sharp on retina screens.
3024 × 3024 → 400 × 400Email attachments under a limit
Bring a folder of photos under a 5 MB email cap by scaling to 50 percent — no quality loss visible at letter size.
50% scale across folderPrint-ready dimensions
Resize to the exact 300 DPI pixel count your print shop requires for postcards, posters, and flyers.

04Pro tips
Get a cleaner resize every time.
Small habits that keep the output crisp, the file size honest, and your workflow fast.
- 01
Keep the ratio locked
Unless you are intentionally stretching, leave the ratio lock on. The two dimensions follow each other and you avoid the classic squished-portrait look.
- 02
Resize down, not up
Shrinking an image is lossless to the eye. Enlarging past the original is always blurry — start with the largest source you have.
- 03
Use percent for bulk-like work
When you need a consistent feel across multiple photos, switch to percent and apply the same scale to every file in turn.
- 04
Compress after resizing
A 1080 × 720 JPG out of resize is still ~300 KB. Run it through the image compressor for another 50–70% off with no visible loss.
05Loved by
Shop owners, devs, and photographers rely on it.
Every product photo I take is 12MP. Wirelogs scales them down to 1500px on the long edge in a single click — pages load in half the time now.
I drop a folder of sprite sheets in and resize to 25% for thumbnails. Zero upload, zero waiting, runs offline once the page is open.
Clients want previews under 2MB. Resize to 50%, save out a JPG, done. Faster than dragging the same file into the cloud tool I used to use.
06Questions
Image resizing, answered.
Quick answers before you resize your first photo. Anything missing? hello@wirelogs.com.
01Does resizing reduce the file size?
Yes, almost always. A smaller image has fewer pixels to encode, so the JPG, PNG, or WebP you download will be lighter than the original. For another round of savings, pair this with the Wirelogs image compressor.
02Will resizing make my image blurry?
Scaling down preserves visible quality — your eye cannot see pixels you no longer need. Scaling up past the original size will look soft because the tool has to invent new pixels. Always start from the largest source you have.
03Which image formats can I resize?
JPG, JPEG, PNG, WebP, AVIF, GIF, BMP, and HEIC up to 50 MB. The output keeps the same format as the input, so a PNG goes in and a PNG comes out.
04How do I keep the aspect ratio?
Leave the lock toggle on — typing a new width auto-updates the height (and vice versa) so the proportions match the original exactly. Turn the lock off if you want to stretch or squish on purpose.
05Is the resize tool truly free?
Yes. There are no usage caps, no watermarks, no upsell flows, no premium tier, and no sign-up. Use it as often as you like on any device.
06Are my photos uploaded somewhere?
No. The resize happens entirely in your browser using the Canvas API. Wirelogs never receives the file — sensitive snapshots, document scans, and personal photos stay on your machine.
07Can I resize multiple images at once?
The tool runs one image at a time today. Re-running the same percentage across files is very fast, and a batch mode is on the roadmap.
08Does it work on mobile?
Yes — the resizer works on iOS and Android browsers, accepts touch drag-and-drop, and supports the share sheet to save to Photos or Files.
