Archiving phone photos

What to expect
The target is preset to 1 MB (1,000,000 bytes). Most phone photos keep full or near-full dimensions at this size; JPG quality is lowered only as much as needed, and dimensions are reduced only if the limit still is not met.
Limits apply to both input and output. Animated images are not supported. Files remain in memory only; reloads clear your work. Smaller batches help on mobile devices.
Frequently asked questions
How do I compress a JPG to 1MB?
Add the photo; the 1 MB target is preset. The tool finds the highest JPG quality that fits and reduces dimensions only if necessary, so results stay as sharp as possible.
Will the photo keep its original size?
Usually yes. At 1 MB most phone photos keep their full dimensions or are reduced only slightly. Choose Keep dimensions to never change the pixel size.
Can I compress PNG screenshots to 1MB?
Yes. PNG and WebP images are converted to JPG to reach the size limit, and transparent areas are filled with the background color you choose.
Can I compress many photos to 1MB at once?
Yes. Add up to 20 photos; each one is compressed to the same limit, and you can download them together as a ZIP.
Are my images uploaded?
No. Image processing takes place in your browser. Files are not sent to Codia and are removed from this workspace when you refresh or leave. Website analytics, when permitted, never contain your images or file names.
Can I process multiple files?
Yes, up to 20 files per batch, within the displayed size limits. Each file is processed separately. Download successful results individually or as a ZIP; a failed file does not block the others.
Will quality and metadata stay the same?
Results depend on the operation and settings. Lossy compression changes pixels; JPG removes transparency. Exports target ordinary 8-bit web images and do not promise EXIF, HDR, original color profiles or 16-bit preservation. Always inspect the result.
