STILL IMAGE GUIDES

In this guide

Reduce a photo’s dimensions and file size from a mobile browser. Use local processing, a target KB limit and a clear preview before saving.

Choose the photo in your browser

Open the image tool on your phone and use the file picker to select a photo. The browser may show recent files, a photo library or cloud-backed items depending on your device. Once chosen, Still processes the file in the browser; it does not upload it to the site.

Set the requirement that matters

If a form gives exact pixels, enter those values and keep proportions locked unless the guide asks for a crop. If it gives a maximum KB size, enter a target. If both are specified, satisfy the dimensions first and compare the file limit second.

Wait for the real preview

Large images take longer on a phone because decoding and encoding use device memory and processing power. Still shows a rendering state while the browser encodes the selected image. It does not invent a progress percentage. If an image is too large for the device, try a smaller source copy.

Save and confirm the result

Use the download action, then find the output in your browser’s downloads or file app. Check the extension and size before attaching it to a form. Mobile browsers handle downloads differently, so the final location depends on your device and browser settings.

Protect the original

The tool makes a separate output file. Keep the original if you may need another crop or format. Avoid repeated exports from an already-compressed copy, and check the official upload instructions before submitting personal photos.

Choose a local copy from the picker

On iPhone or Android, the browser's file picker may offer recent files, the photo library or a cloud-backed provider. Choose the image you want to process and wait for the preview. The browser may first need to read a large camera original into memory. If the phone is low on free memory, make a smaller source copy in Photos or Files and start again.

Set the exact requirement first

If the upload form gives a pixel width and height, enter those values and keep proportions locked unless it asks for a crop. If it gives a maximum in KB, set that target and review the final measurement. When both values are specified, dimensions are a separate rule from byte size. Do not assume that a smaller file automatically has the right shape for the form.

Allow the phone to finish processing

Image decoding and encoding use the phone's processor and memory. A large panorama can take longer than a small screenshot, particularly when target mode needs several actual encodes. Still shows a rendering state without a made-up percentage. Keep the tab open until the download action becomes available, and try a lower output dimension if the phone reports that the image is too large.

Find the download after saving

Mobile browsers can place downloads in different locations. On iOS, a saved file may appear in the Files app or browser downloads; Android often offers a Downloads folder or system notification. The exact behavior depends on browser settings. Check the downloaded filename, extension, dimensions and size before attaching it to a form so the original and export are not confused.

Protect the source photo

The local workflow avoids sending the selected image to Still, but a photo may still be saved by your browser in its normal download history. Keep the source in a safe location, and submit the finished copy only to the intended service. If you use a shared phone, remove extra temporary copies when appropriate and avoid leaving sensitive photos visible in recent downloads.

Use the browser's file picker deliberately

A mobile picker may display camera photos, recent downloads, Files folders or cloud providers in one view. Check the filename before selecting so the browser receives the original you intended. Very large phone photographs can have dimensions well above what a small form needs. Still caps input size and pixel count to reduce the chance of a browser memory failure, but the available headroom differs by device.

Make a smaller output for the actual destination

Enter the requested width and height from the form, or choose a practical display size when no exact dimensions are given. A smaller pixel grid can often reduce transfer size more cleanly than lowering quality on a full-resolution camera image. If a strict KB target is required, run the target search after choosing the correct dimensions and inspect how the result looks.

Keep the screen awake during a large export

A phone browser may pause work if the tab is closed or the device moves to another app. Stay on the page until the preview is ready, especially for a batch or a large photo. The app does not show a fabricated percentage for a single encode; wait for the actual result and download control. If a processing error appears, reduce output dimensions or choose one file at a time.

Check orientation and file details

Phone cameras can store orientation metadata separately from pixel rows. Still uses the browser's image decoder and offers rotation controls, so inspect the preview before saving. Confirm the output extension and dimensions after download; the files app may sort the export next to the source with similar names. Use descriptive filenames for a form photo and signature so they cannot be attached to the wrong field.

Use private storage for identity photos

Local processing means the photo is not uploaded to Still during conversion, but a downloaded copy becomes an ordinary file on your device. Keep it in a location you trust, and avoid leaving sensitive photos in a shared downloads folder. When attaching it to a government or exam portal, navigate to the official service and follow its current upload instructions. A local compressor cannot validate that destination on your behalf.

QUESTIONS, ANSWERED

Frequently asked questions

What should I check first when I how to reduce photo size on a phone?

Reduce a photo’s dimensions and file size from a mobile browser. Use local processing, a target KB limit and a clear preview before saving.

Will changing the file size restore image detail?

No. Compression and resizing can reduce bytes or dimensions, but they cannot recover details already missing from the source.

Are image requirements the same on every website?

No. Check the current instructions from the service that will receive your file, including its format, pixel and byte limits.

Does Still upload the image while I follow this guide?

No. Still uses browser Canvas for image processing, and the source stays on your device.
