A 1 MB limit is one of the most common rules on the internet: visa and immigration portals, job applications, insurance claims, school and government services, support tickets and many email workflows use it. It is generous for a well-compressed photo, yet modern phones produce 3–6 MB images and 48-megapixel modes far more, so originals are routinely rejected.
This tool brings photos and scans under 1 MB while keeping their full resolution and practically all of their detail. The target is preset above; drop in your image and download a file that fits. It runs entirely in your browser, so nothing is uploaded.
Before
Phone photo, 4032 × 3024
≈ 4.5 MB
Rejected by forms and services with a 1 MB cap.
After
JPEG, same dimensions
≤ 1 MB
Full resolution; differences invisible at normal viewing size.
Illustrative example. 1 MB gives about 0.7 bits per pixel even at 12 megapixels, which is enough for an excellent JPEG.
The Target Size tab above is preset to 1024 KB (1 MB).
Drop a JPEG, HEIC, PNG, WebP, TIFF or other image. It stays on your device.
JPEG is accepted by every form and service. Use WebP or AVIF only for your own website.
The engine finds the highest quality at or under 1 MB. Check the preview and download.
| Dimensions | Megapixels | Bits per pixel at 1 MB | Expected result |
|---|---|---|---|
| 3000 × 2000 | 6.0 MP | ≈ 1.4 bpp | Practically identical to the original |
| 4032 × 3024 | 12.2 MP | ≈ 0.69 bpp | Excellent |
| 6000 × 4000 | 24 MP | ≈ 0.35 bpp | Good |
| 8064 × 6048 (48 MP phone) | 48.8 MP | ≈ 0.17 bpp | Fair; resize first |
| Scanned A4 at 300 DPI (2480 × 3508) | 8.7 MP | ≈ 0.96 bpp | Very good for documents |
One megabyte (1,024 KB) is about 8.4 million bits. A 12-megapixel photo then gets around 0.7 bits per pixel, comfortably within the range where JPEG looks excellent. At 6 megapixels it is about 1.4 bits per pixel, effectively indistinguishable from the original.
Only very high-resolution images struggle. Phones with 48- or 50-megapixel modes and professional cameras produce so many pixels that 1 MB spreads thin. For those, resizing to around 4000 pixels wide before compressing gives a visibly sharper result at the same size.
Portals often ask for scanned documents under 1 MB. A 300 DPI A4 scan is about 8.7 megapixels, which fits 1 MB as a JPEG with crisp, readable text. A few habits help:
Computers traditionally count 1 MB as 1,024 × 1,024 = 1,048,576 bytes, and this tool does the same. Some websites count 1 MB as exactly 1,000,000 bytes, which is about 4.6% less. If a portal rejects a file that your computer shows as 0.98 MB, that is why. Set the target to 976 KB to stay under 1,000,000 bytes on any site.
The compressor searches JPEG quality in up to nine steps, measuring each result and keeping the largest one at or under the limit. It never returns a file above the limit when a fitting quality exists, and it keeps your original width and height. If a file is already under 1 MB, upload it as it is; recompressing only loses quality.
Visa documents, IDs and claim photos are sensitive. This tool compresses them on your device using the browser's own encoder; nothing is uploaded. The output carries no EXIF metadata, so the photo's location and device details are not passed on.
Many portals apply the 1 MB limit per file. If you need to submit a multi-page document, compress each page image first, then combine them with the Image to PDF converter; ten pages of 100–150 KB each make a PDF of roughly 1–1.5 MB, so adjust page sizes to stay within the portal's PDF limit as well.
If you regularly need small photos, phone settings help too. Recording at a lower resolution, turning off high-resolution or "ProRAW"-style modes for everyday shots, and choosing JPG instead of HEIC on iPhones (Settings → Camera → Formats → Most Compatible) all produce files that need less compression later.
Confirm the downloaded file in your file manager rather than relying on the number shown in the browser. On Windows, the Properties dialog shows the exact byte count; on a Mac, Get Info does the same. Compare it with the portal's limit, remembering that some sites count 1 MB as 1,000,000 bytes, and make sure the file name and format are what the form expects.
Many recent phones can shoot at 48 or 50 megapixels, producing files of 10–20 MB. Squeezing that many pixels into 1 MB leaves under 0.2 bits per pixel, which softens fine detail. Most portals and viewers never display more than a few megapixels, so resizing to around 4000 pixels on the long side with the Image Resizer before compressing gives a sharper result at the same 1 MB.

Attach several high-quality photos to one message.
Drop it into the workspace above, where the target is preset to 1 MB, and download the result. The engine picks the highest quality that keeps the file at or below 1 MB, without changing its dimensions.
Hardly. At 1 MB a 12-megapixel photo gets about 0.7 bits per pixel, enough for a high-quality JPEG. Differences are invisible at normal viewing sizes.
This tool uses 1 MB = 1,024 KB = 1,048,576 bytes. Some sites count 1 MB as 1,000,000 bytes; if a site rejects a file just under 1 MB, set the target to 976 KB.
Yes. HEIC files are decoded in your browser and saved as JPEG under 1 MB, which also solves the "HEIC not supported" problem on many forms.
Yes. A 300 DPI A4 scan usually fits under 1 MB as a JPEG with clear text. If a form wants a PDF, convert the compressed image with the Image to PDF converter.
No. Everything happens in your browser; the image never leaves your device.
Very high-resolution photos have too many pixels for 1 MB to keep every detail. Resize to around 4000 pixels wide with the Image Resizer first; the result will look sharper at the same size.
No. The compressed JPEG has no EXIF metadata, so GPS location and camera details are not shared.
Yes. Choose JPEG or WebP output and the compressor will fit it under 1 MB; PNG output keeps its lossless size and may not fit.
Colours stay the same to the eye. Very wide-gamut photos may look very slightly less saturated in some viewers, as the browser exports standard sRGB.
Compress the page images first, then combine them with the Image to PDF converter, and use its compression setting to keep the PDF under the limit.
