Converting Photos and a Multipage TIFF to JPG: What to Check Before You Send the Files

When you need to pass several pictures to someone else, a ZIP download is convenient. It is also easy to treat the ZIP as proof that every source picture made it through. Before you send it on, take a few minutes to check the results against the pictures you meant to convert.

This matters most when the selection mixes ordinary photos with a multipage TIFF. One source can produce several JPGs. Another source might fail. If a run stops, the result for one source might not be kept, and later sources might not be processed. The number of files in the ZIP can't tell you which of those happened.

Start with a short source list

Before converting, note the source files and what each should contain. For a multipage TIFF, note the pages you expect. If two files have similar names, add a description such as “front view” or “label close-up” so you can tell them apart later.

To convert a mix of photos and TIFF files to JPG with LensUp, check the tier limits first: the free tier handles one source image at a time, and Pro allows up to 50 sources in a batch, subject to the tool's limits. A multipage TIFF is still one source, even if it produces several images.

Select your images and look for selection messages before you continue. A file can be skipped at this stage, so the list you meant to select and the list that goes on to conversion may differ. Keep the original files until you have checked the finished handoff.

Convert, then read the result

Leave Maximum KB per image empty unless you have a size requirement. If you enter a target, the converter adjusts quality on a best-effort basis and does not shrink the image dimensions to meet it. A converted image can still miss the requested size, so check the result's size message.

Keep photo details (EXIF) is optional and off by default. Turn it on only if keeping the available photo details matters for your handoff. Leaving it off is not a substitute for a separate metadata inspection when one is required.

Select Convert to JPG. Read the status and any listed failures before downloading. Other images in a batch may continue when one fails. A progress warning can also say the run stopped because the accumulated JPG output would exceed the batch budget. In that case, the result for the source where the run stopped is not kept, and later sources are not processed, so both need another run.

Open the files, not just the folder

With at least two successful output images, a ZIP download is available. With one output, download the JPG individually. If creating the ZIP fails, the page advises trying again or downloading the individual JPG files.

After downloading, open the images and compare them with your source list. Check that the expected subject and, for a TIFF, the expected pages are present. Look at important details at a useful size. JPG is lossy, so a successful conversion is not itself a judgment that the image is suitable for its destination.

Next to your list, mark any source that failed, was not kept, or was not processed. Convert those separately when possible, and check their results too. When you send the files, add a short note with the list and any unresolved exceptions.

How to print an ID card front and back on one page

Image
ID cards are 85.60 × 53.98 mm. Print dialogs default to “fit to page”. Put those two facts together and your copy comes out oversized. There is a small errand almost everyone runs eventually: an office wants a copy of both sides of your ID card on a single sheet of paper. A bank, a landlord, a university, a visa centre, an employer. The instruction is always short — "both sides, one page" — and it sounds like the easiest thing in the world. Then the copy comes back rejected, and nobody tells you why. Often it is not the photograph at all. It is the size. Identity cards have an exact size, and the person checking knows it Almost every national identity card in the world is the same physical object: 85.60 × 53.98 mm . That is a real standard — ID-1, the same format as the bank card in your wallet.
