JPEG Usein kysytyt kysymykset konversioista
What is a JPEG file?
+
JPEG is a lossy raster image format. The encoder discards visual information the human eye is less sensitive to in exchange for dramatically smaller file sizes than equivalent lossless formats. Recompressing a JPEG repeatedly causes cumulative quality loss, so always edit from a lossless master where possible.
When should I convert JPEG to another format?
+
Convert JPEG to PNG, WebP or TIFF when you need an image with no further lossy compression — for archival, for editing, or when the target medium (print, banner ad, product photo) demands maximum fidelity.
Will converting JPEG reduce image quality?
+
Converting JPEG to a lossless format like PNG locks in the current pixels with no further loss. Converting JPEG to another lossy format causes generational quality loss because the new encoder re-encodes already-lossy data — keep the source if you plan to edit further.
Does MOV.to keep my JPEG files private?
+
Your JPEG files are processed over HTTPS, never read by humans, and deleted from our servers automatically after conversion. No watermarks, no email signup, no resale of image data.
How large a JPEG file can I convert?
+
Free users can upload JPEG files up to 100 MB. Pro users go up to several GB per file and can batch-convert many files in one job.
Can I convert JPEG on my phone?
+
Yes. MOV.to runs entirely in the browser, so iPhone, iPad and Android users can convert JPEG files without installing any app. The result downloads straight to your camera roll or downloads folder.
Do I need Photoshop or any other software for JPEG?
+
No. The conversion runs server-side. You upload JPEG, pick the target format, and download the result — no Photoshop, GIMP, ImageMagick or local install required.
Can I batch-convert many JPEG files at once?
+
Yes. Upload multiple JPEG files in a single drop and MOV.to converts them in parallel. Free users can queue a couple at a time; Pro users have unlimited batch conversion.
Is converting JPEG on MOV.to free?
+
Yes — single-file JPEG conversion is free with no signup. Pro features (very large files, batch jobs, OCR, advanced edits) live behind an optional plan.
What output format gives the best result for JPEG?
+
For web delivery, convert JPEG to WebP — smaller files, similar quality. For editable masters, use PNG or TIFF. For email and broad compatibility, JPG remains the safe default.
