A job applicant has a 6MB phone photo of their passport that needs to fit a job portal's 1MB upload limit, without becoming illegible.
The Walkthrough
- Upload the original photo
Start with the original 6MB file rather than a pre-shrunk version, since compressing from a lower-quality copy tends to lose more legibility for the same target size. - Start with a moderate compression level
Rather than compressing straight to the smallest possible size, start at a moderate setting and check the preview — extreme compression risks blurring small text like passport numbers. - Check the preview at actual size
Zoom to the actual size the portal will display or store the image at, not a magnified preview, since that's the resolution that matters for legibility checks on the receiving end. - Adjust until under the 1MB limit
Increase compression incrementally until the file size is comfortably under 1MB, checking legibility at each step rather than jumping straight to maximum compression. - Download and verify before uploading
Open the compressed file separately to confirm all text and photo details remain clearly readable before submitting it to the portal.
The Takeaway
The goal isn't the smallest possible file — it's the smallest file that stays comfortably under the limit while remaining fully legible, which is why checking the preview at each compression step matters more than jumping straight to maximum compression.

Frequently Asked Questions
Will compression make small text on my ID unreadable?
At moderate settings, no — the compressor is tuned to preserve legibility; extreme compression settings are where text and fine details start to blur.
Does the file format affect how well compression works?
JPG generally compresses photographs more efficiently than PNG; if your original is PNG, converting to JPG first can sometimes achieve a smaller size at similar quality.
What if 1MB is still too large after maximum reasonable compression?
Consider resizing the image dimensions first (using an image resizer) alongside compression, since a smaller pixel size compounds with compression to reduce file size further.
Is it safe to upload a compressed ID photo for official use?
As long as all details remain clearly legible in the compressed version, moderate compression doesn't affect the document's validity for most upload purposes — check the specific portal's requirements if in doubt.
Does compressing an image remove any personal data (EXIF)?
Compression tools typically focus on visual file size, not EXIF metadata specifically — if metadata removal matters for your use case, check whether that's handled separately.
