Free photo tool
Resize & compress images
Make a photo smaller, in pixels, in file size, or both, without handing it to a website. Drop in JPEG, PNG, WebP or iPhone HEIC, set a size, and download the result one by one or as a zip. It all runs in your browser. Your photos never leave this device.

Output settings
Keeps PNG/WebP as-is; everything else becomes JPEG.
Shrinks to fit inside these bounds, keeping the aspect ratio. Leave one blank to constrain only the other. Never enlarges.
Higher looks better but weighs more. 80% is a good default.
Optional. For JPEG/WebP, quality is chosen automatically to land under this. Leave blank to use the quality slider.
PNG and WebP output never carry EXIF metadata here. There is nothing to keep, so those come out clean.

How to make a photo smaller without a website that uploads it
Two different “smaller”
A photo can be too big in two ways, and they are fixed differently. Too many pixels (dimensions like 4032×3024): you resize it. Too many kilobytes (the file size): you compress it, usually by lowering JPEG or WebP quality. Often you want both. Scale the dimensions down for the web, then let quality do the rest to hit an upload limit.
Why format matters
JPEG is smallest for photographs and the safe default for sharing. WebP is smaller still at similar quality and is supported everywhere modern. PNG is lossless and keeps transparency, but photographs saved as PNG are large — use it for graphics and screenshots, not camera photos.
Why do it in your browser
Most “resize and compress” sites upload your photo to a server to do the work. Your picture lands on someone else’s computer, with its GPS location and timestamp still attached. This tool does the decoding, resizing and re-encoding inside your browser. The image is never uploaded, never logged, and never leaves your device. Turn your Wi-Fi off and it still works.
See what’s inside first
Want to know what a photo is carrying, such as GPS, device and timestamps, before you resize it? Read its metadata.

Need to black out a face, a screen or a document as well? The photo cleaner redacts pixels and strips EXIF.
Photo cleaner →Questions people ask
Are my images uploaded anywhere?
No. Reading the file, resizing it and writing the new one all happen in your browser on your device. Nothing is sent to any server. After the page loads you can go fully offline and it keeps working.
How do I hit a specific file size, like under 1 MB?
Type your limit into “Target max file size” and pick JPEG or WebP. The tool searches the quality setting for you to land at or just under that size. If it can’t get there even at low quality, reduce the dimensions too. A smaller image compresses to a smaller file.
Will resizing lose quality?
Making an image smaller (fewer pixels) is clean. The tool downscales in steps to stay sharp. Compression (JPEG or WebP quality) is lossy, so lower quality means visible artifacts. At 80% or more the difference is hard to see for sharing. PNG is lossless but won’t shrink a photo much.
JPEG, PNG or WebP: which should I choose?
JPEG for photos you want small and universal. WebP for the smallest file at the same quality, where you know the destination supports it. PNG for graphics, screenshots or anything needing transparency, but not for camera photos, where it balloons the file.
Can it handle iPhone HEIC files?
Yes. HEIC and HEIF are decoded with the same in-browser decoder as our HEIC converter. You can resize or compress straight from an iPhone photo and get a JPEG, PNG or WebP out.
Does it keep the photo’s date and location?
Only if you ask. The “strip metadata” switch is on by default, so the output carries no GPS, timestamp or camera info. Turn it off to copy the original EXIF into a JPEG output. PNG and WebP outputs are always metadata-free here.
Honest notes
Compression is a trade. Every time you lower JPEG or WebP quality you throw away detail to save bytes, and it doesn’t come back if you re-save. Keep your original if the photo matters, and compress a copy.
Target-size matching is best-effort. The tool searches quality to fit your limit. If the picture is complex it may need smaller dimensions to get there, and it will tell you when it couldn’t.
Stripping metadata removes what the file says about itself, not what the picture shows. Faces, signs and reflections stay visible. To cover part of the image, use the photo cleaner.
The full-size originals still live somewhere.
You just made a smaller copy. The originals are still in your library at full resolution. Sealby keeps the ones that matter encrypted on your device, readable by no one but you.
